Weird nvidia tv out problem since 56.64

[Wanglera]

With the new NVIDIA-driver WMP on TV shows black screen though movie is seen on the monitor. How can this be?

I can get the movie to be shown on tv by selecting Fullscreen overlay but i was happier with having it like i had it with last driver, where i could choose to have fullscreen or not on tv.

What could the problem be?

Thanks for help
