I am not sure if I should just add to this thread, or make it a new thread. Anyway, I did do the upgrade to DVD Fab platinum 184.108.40.206, and also use another PC to do the copies, so the reading drive and the writing drive are different. And I still have the same problem. movie beginns to studder at about 2/3 of the movie, and then stops to play altogether. The problem seems to be on this particular player, the copies made by dvdfab are just not good enough? As soon as I put the original movie in, no problem, it plays. The same copy is playing in another player though. Any other suggestions? -Besides from watching the movie from the player in which it works, which is not a convenient option.
