Dual Monitor Issue-Can't drag MedPlay to Second Monitor

Here is my problem. I have a primary monitor and then I run S-Video out to the TV so I can watch video clips.

With Vista, I had no trouble starting a video clip in media player on the primary screen and then dragging it over to the second monitor (TV) for actual viewing.
However, I tried to do that with Windows 7-it won't let me drag Media Player over to the second monitor. I can drag other applications to the second Window (Word, Browsers), but not any media program. Even tried another media player application.

Not sure what to do-how can I get this to work? I want to be able to watch TV/Movies on my second monitor.

Actually update. I have a hard time dragging anything to my second display. I never had trouble dragging things to my second monitor before. When I get to the right edge of my main display, the window dragging stops..I can't get it to the second monitor. What am I doing wrong?

Got it working-changed the resolution of my primary display.
I am all set..
