I did a search for MP4, and didn't get anything hits. So I hope this hasn't been asked before. I have an HTC Droid Incredible and record my video in 720p. When I copy the file to my pc Windows Media Player does not play the audio of the .MP4. The video plays fine however. (All playes fine on the phone) I have a camcorder that also records 720 mp4 files, and it plays audio and video just fine on the same pc. It is possible that another player might play the file fine such as VLC, but I like Windows Media Player, and prefere not to have 3-4 media players taking up resources on my pc. Any suggestions? Thanks.
