I have run into an interesting problem, once this past fall and now it has come up again. First title with the problem was "Casablanca" and now Ihave the problem with the Critereon Collection "Sullivan's Travels". I am trying to play the movie on a PC running PowerDVD software. When I play other movies, they work FINE. Perfectly! When I attempted the above titles, play back was horrible. Extremely choppy. Just unwatchable. The audio was also very quiet compared to other titles. Now, if I launch the RealONE player, and have it play the DVD, the playback is quite good. Although the volume is still a little too quiet (I think, at least). So, my question is: If RealONE is using the same software CODEC as PowerDVD, why is the playback bad in one software, and acceptable in the other? How can I fix it so that I can play the title back in PowerDVD?
