Happy Update..... After Swapping monitors and Dropping 1 DDC pin in my VGA, TVtool now seems to be working flawlessly. It appears that the 4400's output architecture didn't play nice with my monitors in stock configuration. Thanks anyway!!
Has ANYONE managed to successfully enable the TV out function of this card, as I have loaded the latest nVidia driver available, with no result. TVtool is also completely unresponsive, as it will not even execute. Any ideas, Anyone. Thanks!
