Movies Stop Playing

Does the same thing happen if you play it with vlc on your computer?   I’ve tried many many tools over the year, and there are just some movies that have to be dumped/decrypted to the hard disk before using another tool like handbrake/dvdshrink/bytecopy on them.

To be sure I’m redoing one now because bytecopy didn’t copy the whole movie to the mkv, so I’m dumping it with dvd decrytper first.
