If a video is slow, it's likely loaded in too high resolution for your machine. Simply pick a lower res from Youtube's menu. I'd recommend 480p for most G4 machines. 1.67GHz PowerBooks should be able to do 720p. G5 machines should be able to play 1080p. Do NOT enable VP8 or HVC - these need a lot more CPU than H264.
