HTC Sensation video help

[tommytoca]

Hey all, I just got my HTC Sensation from T-Mobile on Friday, shot a couple of videos in 720p, looks great on the phone, but when I copy the files to my computer, it only plays the audio. It's an mp4 file btw, normaly windows media plays other mp4 files just fine. Am I doing something wrong here?

I have somewhat the same issues with my Mac, it will play the video files just fine but there's a odd format where they will not work in iOS devices without being transcoded.
