This is weird. For the past few days my mp4 videos (ripped with DVD Catalyst) will not play. I see the time skipping like it is in fast forward, the screen is blank, and there is no audio. These worked fine up until about a week and a half ago. And always worked great on my D1. I've tried playing them using ES Media Player, Act 1 video player, QuickPic, Video Player. Same problem with all. Any ideas?
