hey all, my family got my dad a very basic sony home theater in box. we have a few gaming systems and a DVD player hooked up through the receiver for him and for the most part it works fine. however, i noticed that when i switch between, say, two different gaming systems, or if there is a sudden white flash on screen, the video signal becomes momentarily distorted. this hasn't been too much of a problem until we watched SW: A New Hope last night where there is alot of flash frames causing the video to jump excessively. all the connections seem secure, so i'm not quite sure what could be causing this. we have an older zenith TV dated from around 1990, but it has never exhibited this problem before hooking up the home theater. any thoughts? thanks!
