I have poor DVD playback quality from my xbox. It cycles from light to dark through an entire movie. Brand new movies not copied. My dvd playback remote is not microsoft. Could that be the problem? My games work fine.
sounds like one of those anti-copy features, macrovision? Is your box's video going thru a VCR? I get that on my dvd player in my bedroom on some retail DVD's. Not many but some. Never on a backup though.
