iMovie exporting to web

[owaters]

I would like to export a movie from iMovie for use on the web. It needs to be pretty good quality both picture and sound but needs to be small in filesize. What settings do you recommend?
Any programs good for compressing movies?

Oh and MP4 (http://www.mp4.com) looks ace!

You'll need Quicktime 6 Pro. It costs $30, but encodes real MPEG4 video.

Is Mpeg4 useable by windows media player?
