lagarith.avi and msud.avi do not decode to identical videos (48.7 dB). Are 
you sure you didn't pick a lossy mode for MSU?

Using lagarith.avi as the source, I get

Converted to yuv in mencoder, except "msud allow colorspace conversion"
which used its own converter. I'm betting that it doesn't just convert
to yuv, but also denoises or something, despite "denoise" being a
separate option.
