Was wondering if anyone has the tuner and has a work around or driver for it. I had this same issue when I went to Vista 64 bit. I am researching GP-PVR as an option, and just not use WMC. I would love to be able to watch/record tv on this system, with the amount of RAM I have, 64 bit is really the only option. Any advice would be appreciated. As far as the "7" experience, everything esle works, and I only get a runtime error every time I open the control panel. I love the pretty new look.
