I had this problem with less than 1% of all my DVDs. Entering the transcode
command in a command line including a certain debug level gave me sometimes
a message about CRC errors in ac3 frames. Skipping these frames worked for me.
I dont't really remember the exact number of frames, but it was always before
the movie started, so nothing was really lost. It's worth to try out different
number of frames. Maybe some kind of copy protection ?
