It was smooth, though it seems as though the framerate drifted below 24fps a couple of times.

This was pretty much peak usage during the space shuttle 720p, though it was normally around 45%. This shows that the background applications that make your system's playback choppy are taken up by the dual core.

Is the h.264 multithreaded, looking at brianG's results it seems not.

I dont think the apple codec is both doesn't mean someone else won't make a multi threaded h.264 codec.
