That is not my experience. I can decode 640x352x25 video with mp3 audio 
on my g4/350 with a vp3 codec (unfortunately it is not the latest 
official codec, which is much slower.) Even With a 1GHz P3, you should 
be able to watch a 320x240x25 stream.

in any case, why would you need to decode at a high speed if you are 
streaming video at very low bitrates... I am a big fan of VP3s, but you 
would not get more than 25fps at 240x320 with only 30kbps to play with.
