I did up a little demo to test the feasibility of running lots of video thumbnails at once. (It's quite feasible.) I put 15 mngs in a kaa.canvas. It ran on my box at about 40% cpu until all the thumbs were loaded (i.e. all had cycled once), and then it dropped to about 22% (because everything was in memory). With opengl after thumbs were loaded, about 16%.

(The evas thumbs looked like about 5 fps, but it's hard to tell.) That's not really that bad, and if you want to generate a 5fps mng then it takes about 3 seconds. Sure it takes ages when you have lots of movies. But that's not _that_ slow when you consider what it's doing.
