This is Pokemon Movie 10, entitled "The Rise of Darkrai", which was aired 2/24/08 on Cartoon Network. The movie has not yet been released on DVD, so this is a capture from the airing.

This is in DivX format and this is the Standard version of the film (It's under 700 MBs, and is of decent quality, which makes this version better for older PCs and media centers). All commercials have been removed and the movie re-spliced together to the best of my abilities using Windows Movie Maker.
