I've tried copy/paste, and on the standard format discs, also tried DVD Decryptor, DVDShrink, and copy disc in Nero.
My drive can do all current formats (other than Blu Ray).

The ones with the wierd directory structure have no Video_TS folder, but have a folder with all the video files that would go in Video_TS if there were one (.vob files, etc.).

At least one set of these are TY discs, which I've burned plenty of myself, and it would seem wierd if I couldn't read them.

In both cases, I'm several people down on the vine, and no one else has complained that they couldn't copy the discs, which leads me to believe that the problem, whatever it is, is on my end.

Thanx for trying to help tho'...
