This post may be like reeeeeaaaaaaaaallllllllllllllyyyyyyyyyyyyyyyyy late, but you might try checking the scripts section. I've heard of a script that allows you to play .avi formated movies in RMXP. Although unless you've got a movie maker that makes avi formats with high quality but low byte usage, or a nice decompression rating on a converter, it would be better to just do the whole pic thing in events. (Generaly avi formats come out as around 150,000Kb or so even for only a 20 sec thing)
