I got these raw AVI files that won't open on my machine. Windows Media Player will only play the audio, VLC player won't play them at all, neither will Vegas 5 edit them and After Effects 6 Pro says "no such AVI compressor".

These are 720x486 size files at 1536kbps.

Ok I figured out it required a v210 codec, so now it plays in WMP and the video (not the audio) opens in Vegas 5, but it will not open in VLC player or After Effects still.
