source Quite portable: weights only 32 kg (70 lbs). As you may have noticed, it has 2 sets of read/write mechanisms, and, from what people said, it was "seen" by the computer as 2 disks. I wonder if it is compatible with ImgBurn...

You couldn't extract the contents even with IsoBuster?

Not with ImgBurn.

Please post the log from when you've tried to read the disc with ImgBurn (you can find it at Help/ImgBurn logs).

It means your burner doesn't support Buffer Underrun Protection.

Open ImgBurn, go to the Mode menu and click Read. If you have more than one burner/reader, make sure the right one is selected as the Source. In the Destination field, click the folder icon to select where the ISO image should be saved. After everything is ready, click the big Read button and wait

The only way I could think of would be by burning that ISO image to a DVD-R/RW with Test Mode enabled (the DVD+R/RW standard doesn't support test mode and DVD-RAM might get overwritten even with Test Mode enabled). Maybe "Calculate MD5" could be added to the Tools/ISO menu for the next version?

DVD Shrink only works for DVD-Video discs. Try using ImgBurn's Read mode to make ISO images from your discs.

If your burner/reader doesn't recognize the DVD then there's nothing that ImgBurn can do.

Use the Build mode to do that. Have a look in the Guides forum if you're in doubt

AUTO means it'll use the Automatic Write Speed Feature, which, by default, burns the disc at MAX speed, and this is not a good idea, especially with dual-layer media. When burning dual-layer media always use 2.4x.

Try upgrading your firmware to the latest version available (1.0B), as your current firmware doesn't support the media you're trying to use.

Please post the full log from that burn (you can find it at Help/ImgBurn logs). The problem is most probably unrelated to the layerbreak.

ImgBurn only reports what it has been informed by your burner, and, for some reason, your burner doesn't like the disc you're trying to use. Go to Tools/Drive/Capabilities and check if that format is supported by your burner. You may also want to check for a firmware update.

Open ImgBurn, click on its Help menu then click on ImgBurn logs

Please tell us where to download that file, so that we can test it and find out what the problem is.

Sorry, but ImgBurn can't do that. You'll have to use Ner0 or some other program that's able to continue a multisession disc.

Not necessarily: it only means that those fields are absent/blank and that no filesystem known to ImgBurn was found. If you're worried that the ISO image could be corrupted, use IsoBuster (or similar program) to open the ISO image and check its contents.

The information is shown as soon as the disc image is selected, regardless of what's inside the burner at that time.

Please have a look at the Guides forum

ImgBurn has no problems reading files from external drives, network drives, etc. The disc image to be burnt is cached in a memory buffer, and the size of this buffer can be adjusted in the Settings (I/O tab).

Please post the log from that burn (you can find it at Help/ImgBurn logs).

Everything is copied from the original disc as-is, sector-by-sector, absolutely no changes are made.

You can't change that in software, as that's an attribute of the media you're using, and as far as I know, there are no recordable PTP discs available, nor any burner that could burn them. Have you tried extracting and re-authoring the content to change the layer break position?
