Flash not transparent under video

Hello, I am working on a site that allows users to upload video’s, in Quicktime or WMV format, and play them back respectively.

My problem is when I try to display the video over a flash animation, the flash animation “eats up” the video when it is playing. The wmode of the flash is set to transparent, and I tried opaque too. Neither help.

Has anyone had a problem like this before?
