I just got the DROID X2 this past week and the first thing I wanted to try was the 1080p playback through HDMI that the original X did not have, so I threw HD mp4 files on and tried playing "cannot play this video" I was confused, so I threw 720p videos from my X and tried playing them "cannot play this video" At this point i'm baffled, did motorola de-support the mp4 codec or something?
