I would seem that Ut Video Codec's performance depends on the CPU architectures.

I was testing on a Core2 Q6600@2.4GHz B0 stepping, 8GB ram, windows XP64. I have another box with a Core2 E6600 but no AMD based machines. The codec seems to mainly use SSE2 assembly, I know Athlon64's perform very poorly with SSE2 but don't know about Phenoms since I've never had one. Penryn and i7s normally get a big boost with lossless codecs (prediction+entropy based) since they love big data caches.
Since it's GPL, I'd be happy to compile a x64 version when the author considers it to be stable enough.
