Hello, here is the problem i having periodically but getting worse. My movie's are starting to skip a frame and freeze up for a few seconds. Lately they have been playing great for first hour but then they start to skip and freeze, sometimes for minutes and become unplayable. I have been using DVDshrink and DVD Decrypter, recently changed to DVD rebuilder and CCE and either nero or dvd clone to burn. I use a Lite-on burner with Ritek G04 disks. I cant really understand this as some movies work fine but others dont at all. Like i said as of late, getting more freezing up on me. Anyone have any suggestions that might help?
