Xbox HD dvd drive and WinDVD

[pmann]

I'm having problems with playback. I have set my 2nd monitor to 1080i resolution using my graphics card's settings (nvidia). I'm using component connection (red, green and blue). How come playback flickers real bad? No problem using DVI but my card only supports one DVI and one D-SUB and the DVI connection I'm using for my primary monitor. I don't want to have to spend for a new graphics card. Can anyone please help?
