Wow, this is great. Already found a use for it. Elsewhere in this forum found the following link where a sample video can be downloaded.

When I tried to open it with the latest Xvid codec I got a mess after the first frame, after installing ffvfw and turning off Xvid with vswap, I got the message that no YV12 decoder could be found on the computer so installed Helix YV12, set ffvfw to decode DivX and no more problems. Thanks! I have already run into several decoding problems with the latest Xvid (It even has trouble decoding at least one earlier build of Xvid) so this new Codec is great!
