Excuse me for sticking into the middle of the discussion, but I have the same problem as the original poster. Accepting that ImgBurn changes *.IFO and *.BUP files for a correct Video DVD, I need at least a method to control if ImgBurn changes those files. So I invented this algorithm:
- "build" mode, create an image file, say MY.ISO;
- extract files from MY.ISO as from an archive;
- check hashes of files;
- if hashes are correct, burn MY.ISO.
So I want to know, can ImgBurn while burning send to an optical drive contents which is different from that in MY.ISO; so files in MY.ISO and files on the optical disk will not match?
