  Don't listen to the nay-sayers.

  A PII/266 with a Rage128(not pro) can sustain 20fps on DVDs under Linux.
There is no good reason a G3/366 can't do the same. And a 500 or 600 should
be able to go all the way.  That is just using the hardware colorspace, not
even using iDCT or motion comp.  
  I have my doubts that Apple is even using those features, because if you
try to play a DVD under OS9 or OSX it will make the system unusable. You
watch the DVD and that's all you do. Might just be playing scheduling tricks
though.
