I'm trying to back-up Shrek according to the guides by Blackout and Raptor and everything is fine until I try to import the .m2v and the .ac3 files into DVD Maestro. The .m2v files imports ok and then it gets parsed. When I import the .ac3 file I get the following warning: "Cannot locate a frame SYNC word at an expected byte offset. Data might be corrupted. [0xc1070042]" Can anyone tell me what Maestro is telling me and how to correct this problem? Also, I used the guides before (without getting any warnings) when I successfully backed-up LotR, Gladiator, and Spider-Man. Any help would be greatly appreciated! Thanks in advance.
