Three problems: 1. Since installing XP sp2 my mercury TV card isn't tuning properly. 2. I have never been able to get the volume control on the TV pop up panel and remote to work. 3. and most annoyingly... I can only use my web cam in windows messenger by changing the settings in options in messenger screen each time, otherwise the TV card is the default device. When I change the settings back to use the TV card again it wont work and I have to reinstall the mercury TV drivers to get it to work. This is a real hassle can anyone help?
