I'm a DVD newbie here. I recently purchased a Zenith XBV243C DVD + VCR combo unit. When I play DVDs that have lots of action sequences, like Star Wars Episode 2 and other flashy movies, there are video glitches when a scene has (typically) quick cuts/flashes. They look like scrambled video. It looks like a small portion of the screen hasn't been decoded properly. I can even pause and use the slow motion play to get to the exact frame where the glitch appears. It only happens for a fraction of a second, but I still notice it. My unit is brand new, and so are the discs I'm using. The discs are perfectly clean. Is this a known problem that occurs with only s-video out, or does using the regular rca video out usually suffer the same fate? Do I have a defective unit, or is this just one of the cons to using DVDs? Thanks a lot.
