Hi,
i need to draw a grid on a video.I have already tried with Windows Media Player control,but so far i havn't been able to draw on the actual surface of the video (i only can draw on the black bands surrounding the video).

Since i am new to using video in apps,i dont even know if i am using the correct approach,and if there's a better control to use.
Can you please give me some good-start advice?Moreover,do u suggest me to use another control?
Thanks in advance!
