I load and play a video with the Direct Show object in Windows (using Build and Run) but if I use the "Set Rate" event it won't change the speed of the video. I have tried 50, 200, 300, etc. and the video plays at the same rate. I've also tried setting the rate before loading the video, after loading it but before playing it, and after playing it but still nothing. Any ideas? Oh, and this happens with AVI and WMV alike.

EDIT: Nope, I just realized I didn't test it with AVI. As soon as I tried AVI it worked. I don't suppose there are any compressed video formats which allow me to change the rate?
