Works fine in Windows Media Player, is that what you are using?
Sorry for the delay. Yes, that's what I'm using but it still just comes up symbols and numbers.
I use VLC. It's a free player that plays *any* video file in the planet.
Also lets you take snapshots of the video and turn video into your desktop wallpaper.
It also streams shoutcasts and bunch of other stuff I've yet to figure out.
