Been having trouble playing my AVS scripts in WMP Classic. I can load the AVS into VirtualDub and it'll play just fine. If I load the script into WMP 6.4, it will accept the file, resize itself as necessary, and state that it is playing. However, the progress bar does not move, the timer in the lower right-hand corner does not advance, and the player simply sits with a blank frame on screen. Any ideas?

EDIT: Just discovered that if I let it sit long enough (30 sec to a minute), WMP will play the audio portion of the file, but still shows a blank frame in the video display.
