I don't know if I'm the only one with 720p mpeg4 play back issues, but it's a bit disappointing to see such a great high end device like the Atrix have these kinds of issues especially with it being such a beast of a smartphone! I put some YouTube videos on my Atrix and I get the dreaded error message and can't play the video. Prior to this I had the HTC Evo which worked flawlessly with HD video. I'm curious if this issue can be fixed by Motorola? I really don't want to have to encode videos since it's a hassle and takes time. If anyone has any suggestions or solutions please feel free to share. I even made a YouTube video about it. YouTube - Motorola Atrix can't play 720p videos???
