  1. Oh hang on, I expect some other site added that line because they knew Tech Spot would just copy + paste it from them.


    Sorry, it was in the change log at Free Codecs. They seem to have a grudge against Tech Spot.

    How are they any better, I wonder? Didn't they "copy&paste" the changelog like idiots? I mean,

    you could put a line in the changelog saying "please remove this line" and it would probably be

    repeated by every site distributing ImgBurn. They're all copy&paste idiots.

  2. Best Buy has these for $35 ($1.40 per disc) on sale this week. Regularly $60.

    I think they're Verbatims, since 8x speed, and the spindle looks like Verbatim.

    Off-brand dual layers are usually just 2.4x speed. Has anyone bought these,

    who can confirm if they are indeed Verbatim? Thanks.

  3. I'm getting a lot of errors during burning. It slows burning down quite some bit. This is the (part of) the log:


    I 15:07:33 Write Speed: MAX


    I 15:07:34 Filling Buffer... (20 MB)


    Increasing your buffer size to 40 or 80 MB might help. Try slowing down the burn speed. I never burn over 8x. I burn 2.4x Verbatim MKM-001 at 2.4-4x. I burn MCC 03RG20 at 4x in my NEC ND-3540A, because that gives the best results. You might also try tweaking settings like a fixed page file size and defragmenting your hard drive. What was the average burn speed?

  4. I guess the .nrg file was done not quite properly, so I extracted its contents with MagicISO and tried to make an .iso with IMGburn:


    Nero and/or MagicISO may be the problem. Try using DVD Shrink to extract the contents to a folder. (Set "No compression" for the disc.) Also, try processing the files with FixVTS or PGC Edit. The original might have authoring or mastering errors.


    Sadly, I don't know where to put a layer break, so I chose the middle position.


    You can test the layer break positions with WinDVD, PowerDVD, DVD Shrink, or other programs. The newest ImgBurn also lets you preview them. It is best if the LB is at a part of the movie with no sound or movement for several seconds. A fade-to-black is ideal. Scene transitions are sometimes OK. You can also create a seamless layer break with Build Mode, if your player supports it. That'll make it less important where you put the layer break.


    I downloaded IFO Edit 0.97 as on some forum suggested, but dunno what needs to be done with that. I guess I need to fix a single IFO file. Any suggestions are welcome.


    IFO Edit is too complicated for a novice. FixVTS and PGC Edit are easier to use. If all else fails, start over or re-author with Shrink.

  5. But that's it - ImgBurn's a burning program, not a conversion one. And ISOBuster is a very good program.


    ISOBuster is a very limited program (EDIT: also $26). I've tried many programs for creating and converting ISOs and very few make images that load in DVD Shrink (the ultimate test for compliance). Most give errors like "invalid UDF structure."


    Importing images into build mode and deleting files can be done bu mounting the appropriate image with Daemon Tools.


    This introduces more possibility for errors. People have already reported problems when using Daemon Tools and ImgBurn together.


    The suggestions, seem, to me, to be a lotta work to satisfy little demand.


    On what basis can you say it would be a lot of work to satisfy little demand? I think most of the work has been done and it would be as easy as plugging one piece of existing code (ISO write) into another piece of existing code (build mode). Please explain.



  6. Now that I think more about it, I think the only instance where the MUX rate may change is when there is a change from one VOB ID to another VOB ID, e.g. from VOB 1, cell 26 to VOB 2, cell 1. So that would indicate that it has to do with the STC discontinuity, which for some (most) DVDs also coincides with a non-seamless flag.


    Many DVDs have a layer break without an STC discontinuity or non-seamless flag. See Criterion and SuperBit titles. All of the new James Bond Ultimate Edition DVDs I've checked have a layer break within the same VOB ID. So do SuperBit DVDs. Blade and L.A. Confidential have seamless layer breaks with one VOB ID. LAC has the STC discontinuity flag set in error. I've never heard of anyone having problems with these DVDs, so the rule seems irrelevant.


    I have to admit that I'm not even sure why the an author would use one mux rate for part of the movie and then finish with a different mux rate, but it somehow seems sensible that some kind of interruption may be necessary to give the player a chance to adjust to the change.
    When this was discussed on Doom9, someone eventually pointed out that not all DVDs have a different mux rate at the LB. If the VOB ID changes, they might, but SuperBit DVDs have a single VOB ID with a high mux rate throughout.


    every pressed DVD-VIDEO that I've looked at with PGCEdit that had mixed mux rates in fact does have a non-seamless and STC discontinuity flag where that occurs. Perhaps only the STC discontinuity flag is needed,


    Try checking Blade, L.A. Confidential, any SuperBit DVD, and many Criterions (Naked, Fear & Loathing). The STC discontinuity flag is may be correct, but the non-seamless flag is unnecessary with most players. Lots of DVDs break the rules and I haven't heard about widespread problems with the titles I mentioned.


    I have seen some pressed DVDs that have a change in VOB ID that happened to have the same mux rate for each VOB ID. However, it seems the STC/non-seamless flags are there also at the transition.
    You should set the STC flag for a VOB ID change, according to Spec. However, L.A. Confidential has the flag set even though a VOB ID change doesn't occur. It also has a seamless layer break. So, the rule seems largely irrelevant.


    As stated above, all pressed DVD-VIDEO discs that I've come across did have STC/non-seamless flags at the transition between mux rates, so how can you be certain that they were authored without regard to the mux rate?


    Only the STC flag is needed, not the non-seamless flag. It is customary, but Superbit, Criterion, Blade, and L.A. Confidential show that it is not required. EDIT. Many DVDs have seamless layer break. That's a separate issue from the STC flag.

  7. It's a hardware thing and should work automatically if the device supports it.

    Do you know of any drives that support over-burning DVD-R? I have a BenQ

    1640 and it won't even try to over-burn them. I can over-burn DVD+R to like

    4650 MB with SolidBurn off. No problem. I read that no drives can over-burn

    DVD-R yet. They need new firmware to allow it. CDspeed's overburning test

    shows that DVD-R should over-burn even more than DVD+R.

  8. I've always believed in buring slow. I burn my DVD5 discs at 4x and my DL's at 2.4. I know it takes a lot more time but it's not like I am standing around waiting for the burns to finsh. The bottom line is that I have had darn near 100% success rate in over 1200 burns.

    The newer 20-pack batches of Verbatim 2.4x DVD+R DL seem to burn better at

    4x. The PI errors are much higher on the second layer if you burn at 2.4x - like

    60 max, 45 average. They play OK, but make me nervous, nonetheless. I burn

    mostly at 4x now, because that seems to give the best results on most DVDs. I

    aim for 97-99 quality scores in CDspeed.


    I only use Verbatim 16x 25-packs and Taiyo Yuden 8-16x (Sony MIJ 50-packs

    with octagonal white spacer). I found that Verbatim 50- and 100-packs do not

    have the same quality as 25-packs. PIEs are twice as much and PIFs are 6-13

    times as much. In short, crappy media. BenQ's Qscan tests also SHOW that the

    Verbatim 25-packs have lower errors than 50s and 100s.


    I would never burn at over 8x. Playback in picky machines can be hit and miss

    if you burn at 12-16x, even with good drives and media.

  9. There is no technical reason re DTS, except the spec says you must have AN AC3 track somewhere on a DVD (at least in NTSC land) - usually a menu or a small extra will suffice. That rule is relaxed in PAL land.


    It doesn't have to be AC3. You can have PCM if you want. Every player supports

    PCM, but DTS is less compatible for people just watching through a TV. I had not

    heard that menus or extras would be adequate. I thought the movie had to have

    Dolby or PCM audio to be fully compliant. That makes the rule almost irrelevant.

    You could have Dolby menus and the movie in DTS only.


    I suspect it is more the influence of Dolby Labs over the DVD Forum than anything else. Nonetheless, I like to be in spec.


    A lot of music DVDs only have PCM or PCM and DTS. If you have the compatible

    equipment, you can author the disc however you want. The DVD spec has lots of

    irrelevant and arbitrary rules, esp with regard to layer break. I have tested with

    seamless breaks and even ECC block/VOBU boundary/NavPack. I've never had

    a playback problem as long as the cell flags and commands were made seamless

    with PGC Edit. The cell flags and commands are key.

  10. Every so often I encounter a DVD title that does not allow the elapsed/total/remaining time to be displayed, whether on the unit itself or in the on-screen display on the televison. Instead it will show only the title number, even when advancing through chapters (so the chapter number is hidden also). Others will show the title and chapter numbers, but no play times. This reminds me of a VCD when under "playback control" mode...


    I assume that this is perhaps a prohibited user operation?


    If it is indeed a PUO, is there a change I can make through IFOEdit or PGCEdit to enable viewing of the title play times?

    I don't think it's a result of a PUO, as that should be removed by most back-up software.

    I think it is because the chapters are split into different PGCs - instead of being joined in

    a single PGC (like most movies are). I've seen this with music DVDs. I use PGC Edit, to

    re-use the cells in a single PGC. Then re-author with Shrink. Otherwise, there is no way

    to fix this issue. It's inherent to how the disc is authored. You can't see an elapsed time,

    because the chapters are split, like VTS 1,1 - 1,2 - 1,3 - etc.

  11. Actually, I've noticed some of the original DVD's layer breaks are set at SPLIP=YES. Just an observation. But I'd use NO when building.

    If you have no problem playing those DVDs past the layer break, why wouldn't

    you want to use the seamless layer break option? It's becoming more common.

    All SuperBit titles use it. This includes stuff like Closer, Panic Room, Adaptation,

    Punch-Drunk Love, and other DVDs that are ONLY available as SuperBit. Many

    Criterion DVDs use seamless layer break, as I've noted - Naked, Videodrome,

    Naked Lunch, Bad Timing, The Man Who Fell To Earth, Fear and Loathing in Las

    Vegas. Also, some Manga DVDs, like Ninja Scroll: 10th Anniversary.


    I've never heard about people having problems with these titles. Most will not

    notice any layer change. It will play smoothly, as it should. If you do seamless

    layer break, I suggest using PGC Edit also. Edit the main movie's PGC to take

    out any cell commands before the layer break. They can cause your player to

    pause or even lock up if they aren't removed. I think they force the player to

    empty its cache, even if the layer is flagged as seamless joint.

  12. Does anyone know of a registry hack or anything that will allow it?

    ImgBurn gives some error message when you try to do it. It won't

    even attempt to over-burn on DVD-R, but it should work in theory.

    Is it a hardware issue that drives simply refuse to do it?

  13. The same could be said for all types of media - infact, every dye type!


    He didn't ask about every type of media or dye type, but that may be a good

    feature. An option to remember the last speed used for a media code. It gets

    awkward when you switch between CD, DVD-5, and DVD-9. Probably using a

    different speed for each type. It would be nice if the program had the option

    to remember the last speed used for each media type. Even better if it would

    remember the last speed for each media code.


    We're probably just dreaming out loud. But who wouldn't want to remember

    the last speed used on each media code? It saves time.

  14. LUK,

    Stupid me I keep forgetting to change the burn rate for DL DVDs. I burn SL TY's at 8x and DL Verbatim's at 6x. Like an idiot I keep forgetting to change the burn rate sometimes when I burn a DL. Is it possible for ImgBurn to remember the settings for each and set last used rate for that type when a blank disk is inserted. I would keep (dumb) people from me from messing up. :(

    Yeah, I have to remember to check that. I like to burn DL Verbatims at their 2.4x

    rated speed, to get the maximum quality. But I burn Verbatim and TY 8-16x at 4

    to 8x. I wish it would remember SL and DL speed...



  15. I agree, but it seems to be out of spec. I also burnb DLs seamless. It's a very good feature.

    Right, it's technically out-of-spec to have a seamless break, but certain

    forms of copy protection are also out-of-spec. When it's done right, the

    seamless LB should work in 95% of players.


    It's like the rule against having only DTS audio for the movie. There is

    no technical reason. It's just for compatibility, because you need a DTS

    decoder. I've seen DVDs that only had DTS.


    I use PGC Edit to set the seamless flag and remove any cell commands

    before the LB. I've found that some players would have a pause on the

    seamless break if there were cell commands before it. Getting rid of the

    the commands increases player compatibility.

  16. Yes, it can and it does... but that's only if you use ImgBurn.


    If you're burning an image from another util, obviously that doesn't even come into it - and I was speaking generally about DVD-R DL media, not DVD-R DL media AND ImgBurn.


    That's what I thought. Also, if you're burning an image in general, it wouldn't

    come into play. Only build mode would have that option. Why would anybody

    here not use ImgBurn now? They would be silly not to.

  17. It is a setting which should be on by default given its experimental nature (for most people who have not yet experimented).

    Yes, it should default to non-seamless break and there should be a warning for

    enabling seamless layer break. I just want to be able to burn seamless without

    having to click it and accept the warning each time. Thanks.


    Since I began using seamless layer break, I have never gone back to doing it

    the normal way. Criterion and Superbit DVDs showed me that seamless break

    works in most players. The rule against it is mostly obsolete.

  18. It is NOT recommended to use DVD-R DL Discs for Video.


    Why not, please? Because it cannot be set to booktype DVD-ROM or what else? I have no clue and just want to clearify here. I favorite DVD-R for all my selfmade videos, I always used Ritek G04 4x or TY 8x only. I need most compatible DVD video disks and the question is now: why not DVD-R DL.


    Compatibility is the biggest problem with DVD-R DL. Reviews by CD Freaks and

    others have shown very low compatibilty, like 25% of DVD+R DL. Many players

    won't recognize the discs. DVD+R with DVD-ROM book type is much more likely

    to be recognized and played without problems. Also, the errors rates tend to be

    higher with DVD-R DL media. If you want good burns, best to stay away. There

    is no advantage to DVD-R DL and a lot of drawbacks.

  19. The layer break (switch) position on DVD-R DL media is fixed, on DVD+R DL media you can move it around.


    So unless your DL image was originally built with a layerbreak at EXACTLY the same point the fixed DVD-R DL one is at, you'll never get a proper burn.

    Can't ImgBurn pad the files in Build Mode, so the layer break lines up properly?

    Or is that not allowed on DVD-R DL? You still might not get a suitable cell, given

    the fixed layer break, but it would be more likely. Right?

  20. I'd like to be able to permanently disable the warning on seamless layer break

    and preferably retain the seamless setting for all of my burns. It's the only way

    I will ever burn a DL image, so I don't need the warning every time or having

    to re-select it every time. Can you please allow it to be turned on permanently

    and get rid of the warnings for seamless layer break? Thanks

  21. Great Software! :) .......I only wish it had one thing.


    I sometimes forget to turn off AnyDVD so it would be nice if ImgBurn would do it for me.

    If you have the log turned on, ImgBurn will warn you. It's not a big deal,

    even if you forget. Only a few bits are changed. The rest would verify ok.

    If you're burning data, it has no effect whatsoever.


    I wouldn't want LUK to turn off other programs without permission. It may

    be better for you to suggest to Slysoft that they disable the program when

    ImgBurn is running, since it's their fault, not LUK's.
