Needed Advice: I have had quite a dilemma with backing up my DVD's for playback in a regular DVD player. I am using an I/O Magic external DVD burner after returning my Sony external burner with similar features. For software I use AnyDVD to mask encryption, DVD shrink to compress, and Nero to execute burning. I am very confused, because for about 95% of the DVD's I burn, they play fine, menus and all, at first , and then somewhere between the middle and end of the film usaully become corrupted with large pixelated sqaures and become extremely choppy and the sound is un-recognizable, ultimately making the movie impossible to finish. I have tried playing the burned DVD's in different DVD players, and computers and they produce similar effects with all, but not always in the same spots. I also tried using both Verbatim and Sony DVD-R discs. This confuses me because it seems that the problem is how they are read, since the files become poluted at different areas. Also, I just installed a generic internal burner in my friends desktop and he's using the same exact software and it works perfect for him. Please help! any advice is appreciated.
