I'm running Windows XP, on an AMD Athalon 64 FX-53 chip, nVidia 6800, Firefox 18.104.22.168, with the latest directx driver. Whenever I would attempt to view an embeded video file with the windows media player, I would recieve this error message, "Can not create DirectShow Player" This also occurs when I use IE or Opera. But when I choose another format (MPG, Flash, AVI, QuickTime) I can see the clip fine. In an attempt to fix this, I removed and reinstalled Windows Media Player 11 Beta. I also tried reinstalling WMP 10 but tht didn't fix it either. (XP users can no longer roll back to version 9. It's been deleted completely) Now not only do I get the "Cannot create DirectShow player" message. I can't even start up Windows Media Player. When I click on the little WMP icon, my cursors flashes an hourglass, than goes back to a cursor. WMP wont engage at all. Help?
