All the movies worked fine that I copied in my regular DVD Player. I just bought a Samsung DVD-HD870 upconvert DVD Player. I've tried watching 3 movies that I copied using ANY DVD and I get picsilating and junping over complete sections of the DVD. I also get unbalanced sound (not synced with the picture) As I write this I'm watching a DVD that was not copied and so far have not had the problem. Samsung said it shouldn't happen and are sending me a new replacement. Is there anything I can do or is ANY DVD copied discs not able to work with upconvertion. I'm watching everything on a new Dell 37" LCD HDTV. If worse comes to worse I'll keep the samsung for uncopied movies and get anothe non-upconvert for the copied movies if I have to. PLEASE HELP ME???? Thanks in advance for any info you may have.
