what amazes me is that DivX puts both of them to shame, and this is done by a company with very little cash income (in comparison to Apple and Microsoft). You'd think with all their millions (billions) of dollars they'd be able to produce media codecs that compare to Apple. I too have noticed QT MPEG-4 blows the big one (AAC sounds cool, but is still nothing spectacular, until it uses 5.1)
 
I agree with this comparison. I would probably not use QuickTime to encode anything streaming - However, for high-bitrate video clips, I find QuickTime is very acceptable.

I'm a little split on DivX, however. I like the codec, but I couldn't playback anything on my old Windows box. It would blue-screen about 5 minutes into any DivX encoded clip, which leaves me to believe that DivX doesn't work with some video cards/system configurations.. So far, on my iBook, it's been good. But I don't know if I would rely on DivX.

Windows Media? Ha. I didn't even know that there was no Mac encoder available. I wouldn't even use it if there was one.
