Asking again for anyone with similar problems or suggestions. I can make a backup bd-re 50gb disc that plays fine on the computer all the way through with powerdvd, but if I take the same disc to the ps3 it will only play 1st part of movie the freezes, and I can't go to a scene towards the end of the movie. Is there some setting I am missing? I did get Cars to work on the 50GB, and Hostel II. Thanks for helping.
