It is not that quality. I dont know decoding algoritms. But I have a film encoded bu Xvid.
Video Codec
     Aspect ratio: 592 x 320  (1.850 : 1)
     Frame/Sec   : 25
     Avg Bitrate : 1175 kb/s

I think quality is sufficiently enough. My Celeron 466/440 BX buddy does a good job.

AFAIK, it does not support PPC platform...
