codec

Recently I've hit a few snags playing some videos, they're everyday .avi videos but I guess they're compressed weirdly 'cause my 'Media Player Classic' can't play them. Soooo I need to know some good codecs for it I'd really like to watch these videos...

Thanks in advance!

VirtualDub also shows the codec IIRC, or at least the fourCC code.  Then it's just a matter of finding it.
