I ripped a DVD movie using SmartRipper, DVD2AVI, TMPGENC, DVDit for Vaio, and Passi PrimoDVD. I burned it at 1x speed. The movie quality looks fine, and when I play it back on my computer's DVD player it plays back fine. However, when I play it back on my Samsung DVD player, it has problem points. At those points...it sometimes just glitches (audio and video) or it skips to a completely different part of the movie. This happens about every 2-3 minutes. Any idea how I can fix this???? Thanks for your help.
