VT37A not sending video and video crashing Showtime

[slint13]

I just installed the VT37A VGA video sender and it works great....with still pictures.  I can get a shot of my Desktop and I can use Showtime to view pictures.  But when I open a video in a media player, the window it opens in goes blank and if I try to open a video in Showtime it crashes the program.  It all looks fine on my PC monitor and I'm using movies in approved formats(avi, mpeg, wmv).  I've connected my video sender through a second port on my Nvidia graphics card and used the clone option to send the signal to my TV.  Does anyone have some suggestions?

Could it be your "clone option" isn't working correctly?
