I have the same problem with my ATI card. The solution (work-around) was to close the player with the window in the second monitor and relaunch the player again and the video shows up again.

I've seen this problem with ATI's USB TV card before. I think the way they fixed it was to force a redraw on the screen when it detects window is greater than the current single monitor resolution. They hardcoded it. Since BSPlayer has a setting for screen size, it could test to see if window is not in x, then redraw.
