I'm messing around recording gameplay with MSI Afterburner. I've recorded one clip and uploaded it to YouTube:

In trying to get better quality, I remembered I didn't have AH set to 1920x1080 (doh), so I adjusted game settings and tried again. Now when I try to upload my Afterburner footage to Sony MS 12, it gives me an error message basically saying "It's an AVI, we ain't doin' it, please jump off a bridge".

The files play perfectly in Windows Media Player though.
Lots of stuff on the web about the issues with MS 12 and AVI files, but they seem to be all over the map. Most say to download a codec of one variety or another, but there doesn't seem to be one solid answer. Anyone here had this issue?
