I had an mp4 vid on my laptop that I transfered to my phone and the video didn't play but the sound did. fortunately I had the same in another format (and better quality) too. downloaded handbrake and used it to convert it to mp4 then transferred that one to the phone and it plays great. also downloaded an hq vid from youtube on the phone and it plays with no prob too. ya might try downloading handbrake and reconverting your video with it. just do mp4 to mp4 conversion. I've had to do things like that before with other devices for whatever reason. btw I'm using the stock player on the phone.
