how in the heck did you get a 1.66ghz G4 to play youtube?

I have a 1.9ghz G5 and it doesnt play youtube worth a crap. and my 1.25ghz G4 ibook isnt even watchable. you have to let it download all the way or it gets stuck ont he first frame. and when its done downloading, it plays VERY slowly. put put put put puttttt 2FPS.
