Ya, I've tried many players, and it seems that this CODEC is a nightmare for everyone. Most discussions on it are from 2002-2006. I'll hop on it again this afternoon. There were some players that would work for this CODEC but that haven't been in operation since 2007 and are no longer supported and the download links are removed.

Found these but I have no idea how to use them.

I was thinking of changing the extension as well. It works for some mkv's.
Looks like we've been searching in similar places Photon... I'll try that player later today.
