Well, ok. Thanks for recommendations. But as I said in the first post, I've tried to burn the same image onto the blank from the same box. With Alcohol 120%. And the disk reads fine. While both of ImgBurn's have an error. Can't that be some misinterpriting of Alcohol's MDS format by ImgBurn? I'm planing to burn another couple of the similar disks with Alcohol. If you're interested I could post results here.

I'm sorry. I didn't really expect that I'd be able to find logs history for CD burn software. Even more respect to ImgBurn since it has such decent logging. Here is the log with the problem: I 20:18:34 ImgBurn Version 2.3.2.0 started!

I've tried to burn a couple of DL disks from ISO+MDS images with the latest ImgBurn version (2.3.2.0). And they both have an error. When trying to read them back one file on each disk (I guess the one that is at the layer break point) has a read error. When burning the disks I remember there was a warning message in the log. Something like buffer underrun (don't remember exactly). And again it seems it was right at the layer break point. Later I tried to burn the same image with Alcohol 120% and the disk reads fine. So the question is: is there anything I can do to help you spot the problem and fix it in the next version? (hope it will be released quite soon ) Or if it's just my hands could you please help me find what needs to be changed (in my settings?)
