OTP Versus PTP...help with ImgBurn Error

HereToday · April 24, 2006

I am a new user of ImgBurn and need some help with next steps. Let me first say that I am a long time user of DVDD so I am familiar with the interface and settings.

I have an .ISO/.MDS combination that I created using DVDD and want to simply burn using ImgBurn on a DVD+R DL. When I start the burn I get a pop-up warning that states the following:

Optimal L1 Data Zone Start LBA: None Found! (VTS_01)

This image has not been mastered correctly for burning onto a double layer (OTP Track Path) disc.

None of the cells meet the 'DVD-Video specification' criteria for a potential layer break position.

Do you want to continue anyway?

Well...I'm not the type into continuing without understanding everything. Where did I go wrong? I thought the layer break info was in the .MDS file but I am now thinking that the original was a PTP and the target is an OTP so I need to make some changes but I don't know what/where.

Any help would be greatly appreciated. I've been reading for an hour or so already so if I've missed a thread that explains please just point me to it.

TIA

You'll need to either extract the files from that MDS/ISO combo and rebuild it using PgcEdit, or do the same via mounting it within DAEMON Tools.

You'll need to either extract the files from that MDS/ISO combo and rebuild it using PgcEdit, or do the same via mounting it within DAEMON Tools.

I saw this recommendation to mount the image via Daemon Tools before and tried it. It didn't work because PGCEdit needs to modify the source files (IFO/BUP anyway), and it cannot do that with a virtual DVD-ROM because it is read-only.

Am I missing something? Is there perhaps a way to have PGCEdit copy the needed modifications to the hard drive, and then make on-the-fly substitutions into the rebuilt image?

**LIGHTNING UK!** · April 24, 2006

Good point, I forgot about that

Ok so you'll need to extract them.

Ok so you'll need to extract them.

Thanks for the confirmation, though I was hoping it was possible!

I imagine PGCEdit could likely be modified to compute the needed changes, write just the modified files to a temporary directory, and then insert those changed files into the image as it is being built... I think this is sort of how RecordNow Deluxe does it for recording on the fly while setting the layer break - it doesn't touch the source files.

Thanks for the assistance LightningUK and fordman . I have now gotten past the ImgBurn error message and am burning using a PgcEdit created .ISO with PgcEdit launching ImgBurn.

Now I have another question/problem (!)

During burning I keep getting the following warnings:

W 14:59:15 Failed to Write Sectors 133888 - 133919 - Write Error - Recovery Needed

W 14:59:15 Retrying (1 of 20)...

W 14:59:43 Retrying (1 of 20)...

This is just a small paste from a much larger list of these. I have burned about 5 discs and one didn't have any of these and the other 4 are rife with them. I think it may be bad disks (I'm using some Memorex DVD+R DL's that are RITEK D01-01). I am going to buy some Verbatim next.

Question is this...If it always just gives 1 retry and then continues can I assume that my disk is usable? Does this mean that error recovery worked? Or should I just ditch the disk any time I get a write error of any sort?

**LIGHTNING UK!** · April 24, 2006

With so many in a row, I'd ditch the disc.

Or at the very least, ensure you verify it!

In theory though, if the retry worked, it 'should' be ok.

You'd do well to stop using the Ritek DL discs and just stick with verbatim.

I think you're right about these discs. They're junk.

Now I'm getting the following:

W 15:44:59 Failed to Write Sectors 4082224 - 4082255 - No Seek Complete

W 15:44:59 Retrying (1 of 20)...

I 15:44:59 Writing Image...

I count about 60-70 errors in total. Ritek just lost my business for good :angry:

**LIGHTNING UK!** · April 24, 2006

I assume you've checked for firmware updates etc?

HereToday · April 24, 2006

I just double checked that. I have a Plextor PX-716A running firmware version 1.09 directly from Plextor's site.

I'm stubborn, I'm trying another one right now just to see if I can find a good one or two out of the bunch.

I think this is sort of how RecordNow Deluxe does it for recording on the fly while setting the layer break - it doesn't touch the source files.

Err! It is not sufficient to overwrite the files in the ISO, because the files must be moved, by inserting some gaps between them. This is how the layer break cell is properly anigned with the start of an ECC bloc. Moving the files requires a full rebuild of the ISO image.

Anyway, even overwriting the files at the same position is not a piece of cake.

**LIGHTNING UK!** · April 24, 2006

I think he/we were talking more about you just using those as the source files - i.e. rather than having to actually extract them and taking up another 7gb of space.

Then of course you'd have to write the new ifo files to a temp directory and merge them back in (logically of course!) with the remainder of the (read only) source files from the mounted image, ready for mkisofs to build a new iso.

LIGHTNINGUK,

I have two additional questions now that I have gotten a little further (I now understand PgcEdit's usage, at least from a newbie standpoint ). To impose a little more on your question answering goodwill:

1) I created three .ISO's using the exact same method and the first one gave me the error in my original post that started this thread. I have gone back and used ImgBurn's 'Display IFO Layer Break Information...' on all three and only the first one gives the error. The second and third have layer break information reported back. Why would this be? Furthermore, do the second and third need to be "corrected" via PgcEdit or not since they report layer break info?

2) On 3 disc's now I have gotten a failure during the Leadin portion of the write during sectors 32-63 and ImgBurn fails on all 20 attempts. The disc is still empty so I can cycle the tray and try again but inevitably the later burn errors occur. Is this most likely bad discs or somethings else entirely? I have ImgBurn set to use SPTI - Microsoft. I'm thinking maybe I should try another I/O interface.

Thanks for all the help thus far...still learning.

**lfcrule1972** · April 25, 2006

I hate Ritek DL discs and so do my burners.......

**LIGHTNING UK!** · April 25, 2006

1) If only 1 errors out, the other 2 should be ok.

2) As we've always said, Ritek DL discs are awful.

Changing the i/o interface wont change that!
