I'm trying to build a frame around a video (would like to use VLC, but WMP would work too). The frame will make the video look like an old-timey TV (rounds the corners). However I'm not sure how to make a layer that could allow video to pass through it in some spots, but block the video in others. I've tried using transparencies, however the video doesnt show through, it just shows the form underneath.

Any ideas on how to do this?
