Whenever I play my backups of my dvds, the movie plays perfect until it gets towards the end of the movie. Around that time it starts to break up into cubes and to lock up and freeze. I have a Pioneer A04 that I've had for a year. I use smartripper, dvd2one and prassi primo dvd to backup. I also tried other software such as dvdxcopy express, etc, but it did the same thing. I tried playing the backups on several dvd players, but no change. My firmware version was 1.30, after I started having problems I upgraded it to version 1.41. The problem started a week ago. I've always used verbatim dvdr 2X. I'm running windows XP with 768meg sdram, 1.7gig intel processor. If anybody has any ideas, please contact me, I've tried everything, but a hammer.
