LIGHTNING UK!

How come the drive was USB one minute and then SATA the next?! When connected via USB, it would appear the real error messages from the drive are getting lost (in the drivers / translation between the actual drive -> your Mac OS -> Parallels -> Windows 7 -> ImgBurn). For that reason, I'd stick with SATA if I were you. That said, it looks like that isn't perfect either - it looks like you ran into some sort of timeout when performing OPC and the media somehow vanished! On top of that you had weird failures when performing the sync cache / close track / finalise disc commands. I don't know how this Parallels thing works but do they ever release updated versions / components? Is yours the most recent? It's hard to try and help out when the machine isn't doing what it's meant to.

What OS are you running? I guess you must still be on Windows XP?

Have you tried burning at 4x instead of 2.4x? The drive might actually do a better job at that speed.

Yes, it's done using the normal quick/full erase method. ImgBurn gives you 3 options for the the amount of space you're left with on the disc after formatting/erasing. It defaults to 'Preferred' which then uses the size in the first 'Format Capacity' descriptor - these are listed in the disc info box on the right of the main window. It's called 'Preferred' because the drive lists them in order of preference (according to the manufacturer / firmware or whatever). You can probably guess what the 'Minimum' and 'Maximum' ones mean The 'FT: 0x32' ones are for formatting with spare areas enabled. So 'Preferred' would leave you with 11826176 usable sectors. 'Minimum' would leave you with 7369728 and 'Maximum' with '12088320'. There's no 'Format' command visible to the end user but it's called when you do a full erase (quick erase doesn't apply to BD-R).

I'd expect 24 bit files to be a problem in general. Certainly, the wav file created by decoding the flac file (using the flac command line tool) will not load either - because it's still 24 bit.

Ah I think it might be because they're 24bit. Maybe madFlac doesn't support 24bit flac files... or at least not when it's being asked to output in 16bit?

Even my drive shows up in it and it's a BH12LS38.... so your issue is probably related to your controller. Try flashing in safemode. btw, just as the program warns when you attempt it, 'Test Mode' doesn't work for BD-R. At least not on my LG drive it doesn't.

According to the post here... http://club.myce.com/f61/mediacodespeededit-tool-dvd-writers-114269/index48.html#post2513577 ...your drive has no firmware support for the 'CMCMAG-DI6-000' MID. If you can get the 2.00-03 update flashed to it, you should be ok. http://www.firmwarehq.com/download_1857-file_BH08LS20_2.00-03.exe.html

Correction, the calculation was fine. My brain was just letting me down earlier I look forward to getting the info/files I requested in my previous post. Oh and here's my working out as it stands currently... disc_capacity = 4173824 layer_size = 2086912 start_split = 2038860 end_split = 2086912 max_padding = 2086912 - 2038860 = 48052 image_size = (2 * 2038860) + 48052 = 4125772 Cell 10 absolute = 1423391 + 596055 = 2019446 size for Cell 10 and everything after it = 4125772 - 2019446 = 2106326 = too much for a layer (layer_size) size for start_split and everything after it = 4125772 - 2038860 = 2086912 = exact size of layer (layer_size)

You probably didn't install madFlac properly. It's a pain if you have UAC enabled Try this...

If you look at the 'Read Speed' option on the main Read mode window you should see that it uses (defaults to) 'MAX' for data (data tracks) and '8x' for audio (audio tracks). As it happens, the Optiarc drives support 4x, 10x, 20x and 40x read speeds on CD. You're unlucky in that upon being asked to read at 8x, the drive opted for 4x rather than 10x.

Typically, now I've looked at the code which produces that screen, I think there's an error in the calculation. It's not a calculation which actually does anything though (i.e. prevents it finding LB positions), it's purely for the values put on that screen. If you don't mind, I'd like to build up a replica of your project here so I can see what's going on. I need the final path names of all the folders/files that will be present on the disc (this should just be the usual VIDEO_TS folder and its IFO/VOB/BUP files) and a list of the exact (to the byte) size of each file. Running 'dir' on the directory via the command prompt will do. Then I need you to zip up the IFO files and attach them in your post / upload them somewhere / email them to me.

Maybe this will help? http://club.myce.com/f116/choosing-correct-layer-break-position-imgburn-313692/ If the previewer won't work, try going into ImgBurn's settings -> General -> Page 2 and check the 'Dont Use DirectDraw Overlays' box. Then try it again.

There's no way we can help without seeing a log. If you keep uninstalling the program, that's why the log on the hdd is empty - it gets deleted. Burn a disc and copy + paste the text from the Log window itself.

It's difficult to work out without having all the figures but basically, nothing before 2038860 is any good. That value is calculated by taking into account the maximum amount of padding that can be applied. Cells before that point require too much padding and push too much data into L1.

Would you be reading the disc with the ISO on it in one drive and writing it on another at the same time? I guess you must be or what you're doing is no quicker/easier than just reading a properly burnt disc to a new image and then burning another copy. Then again, I only see 1 drive mentioned in your log so you can't be. There's no difference in drag+dropping the an ISO from a disc to making a new one with ImgBurn's Read mode. You're going to end up with the exact same file on your hdd. It wouldn't matter even if the file system *could* be made smaller, as you've already said, the ISO you're burning is the *exact* size of the BD-R DL discs. You haven't even got 1 sector to spare. You can't do anything to change how much free space there is on a disc. If you zip/rar the file it may well give you the extra bit of headroom you need. It'll take a while to compress 50gb though!

Ok, there's your problem. Your machine is pulling in 5 additional filters that simply aren't required and they're messing up the output. If you've installed one of those codec packs, remove it. They're more trouble than they're worth. All you need is madFlac.

When you burn something in Build mode, you're wrapping the files up inside another ISO container and that involves adding a file system around them. That file system info takes up space, which is why the new ISO ends up being too big for the disc. So for that file, it's simply not possible. ImgBurn detects when you're building a BD Video image and will prompt you if your settings aren't right. There's also a BD Video guide in the guides forum.

Load one of your flac files into the 'Create CUE' window, then right click it and display the directshow filter list. Press CTRL+C when the message box is still on the screen and then CTRL+V (paste) the info into a reply. i.e.

The pink box up the top tells you how to find the saved logs. i.e. http://forum.imgburn.com/index.php?showtopic=14632

I guess because Cell 10 starts before that location (2038860 / 615469) and Cell 11 starts after it (2086912 / 663521). If you pad Cell 10 so it starts at 2038860 you'd end up with more data on L1 than could actually fit on the disc. You need more Cells inserted between Cell 10 and 11. Follow the 'end of the world' guide in the Guides forum.
