ok, post your
anydvd info window so we can see what's on this bad boy.
(sorry for the delay...i was at work for the morning)
unless there's a whole batch of bad disks, it's strange that you got a cyclic redundancy error in the same spot on both discs. even if the disc is new, try cleaning it thoroughly with a soft cloth or try it in a different drive. Some drives are better readers than others.
once you post the anydvd info window, we'll go from there.
