Problem with TV,pleease help!

[cega]

I have a really weird problem.When I play any type of video file(mpg,avi,etc.)I can see everything perfectly on my laptop(Toshiba satellite Pro6100 /w nVidia GeForce4 420GO /w TV OUT),but on TV I still can see everything except a movie window wich is black.I still have a sound,my desktop,menus,even menus directly in BSPlayer,even a green text designating some settings during playing a movie(BSPlayer...EST,etc.).So,the only thing that I can't see is a MOVIE,even I can see the same movie on my laptop screen,in a same time...So,if anyone knows how to solve this,please be so kind...I didn't try to connect second monitor on RGBOut,just TV on TVOut...
