As far as I know, all of the Canon cameras record in the OpenDML AVI compatible motion JPEG standard. Quicktime can play these back, as I'm sure other OpenDML compliant MJPEG players can.

The limits of the composite out would only apply when playing from the camera. Of course, since these videos are compressed on the fly, expect to see compression artifacts on anything but the simplest of subjects. In other words, don't expect DV or Digital-8 quality from these cameras, since they are doing realtime compression at much more that 5:1. I imagine the color resolution is 4:1:1 as well (color at 1/4 the luminence resolution) - as you might expect at this price point.

In general terms, the video I've seen from these cameras approximates VHS or VCD quality - any boost you get in resolution is negated by compression artifacts.

A fun feature to play around with, just don't expect too much.
