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...
