Whenever I try and play a video in fullscreen with Nero7 (Nero Showtime), or my TV tuner card, I end up with sound, yet no picture (black screen). In windowed mode, no problems. If I unload WB5, they play fine. Took me a bit to figure out WB was the problem, but I've tried back and forth, unloading/enabling WB, same result every time (no fullscreen with WB enabled). Have also tried several skins, with the same affect, so it's not a skin specific issue.

Went to the "per application" settings, and added everything in Nero (including Showtime) as well as my tuner card .exe's, checking the ignore this option. No help, still a blank in fullscreen mode.
