I have a few DVD's, like Benaroya or Pinkpop 2000, that play perfectly on a standalone player, but make PowerDVD crash on my PC whenever I try to access chapters (from a setlist menu, with previous/next).

Any idea ? Maybe because I haven't upgraded PowerDVD for a while ?

Another question: huge VOB files are splitted into smaller ones (around 1Go each) called VTS_01_01, VTS_01_02, etc. Is the size of each file standard ? I ask because I tried to seed a torrent on Easytree with a DVD I own, but the size of files didn't match (there was a slight difference, like 500 ko).
