If your picture isn’t looking as good as you’d like, have you tried tweaking the settings via Media Center? You can adjust the critical settings (i.e., contrast, brightness, color, etc.) using the built-in MC utility. If Media Center is your primary method of watching TV then you might want to get a calibration disc, like Digital Video Essentials, and calibrate the settings via Media Center for the optimum picture. I believe the adjustments can be made as part of the TV setup option. Chances are your current video card is fine.
