Whilst on a thread over at macintoshgarden, checking out a low-end video site one user has launched, Cornica I found that on my G3 iMac, videos I'd transcoded (Cinepak and Sorenson 3) actually played with great efficiency - as measured in menumeters and Terminal/top, when dropped into Safari than in QuickTime.
Safari uses QuickTime for playback but somehow is able to outpace the QuickTime player itself - an interesting and unexpected alternative.
