It's easy to get 10 fps playback from MPEG *if you have the right source material*. It's also hard to get beyond 3-4 fps if you have bad source material. I've just about completed 100 hours of measurements on Apple's compact video format and I can tell you that the source material makes a *big* difference in compression ratios, data transfer rates, data decompression, etc. A stable background with only a little movement works much better with these codecs than, say, panning or zooming the camera. Of course, MPEG won't be of too much use to most of us until the hardware codecs come along.
