CentralMedia - The driver updates worked like a champ. AVWizard started after first reboot. Thanks for the sage advice!! As for the beefy card, no offense taken. Thanks again for being interested. The box has 16GB of 2133 RAM and an AMD Phenom II X6 with an SSD drive. Way too much sexiness for this application, but it's just what I have available. I agree with you on the power consumption. Have you tried installing MCE on a DreamPlug or other appliance that doesn't require much?
l3mce - Here's the grep:

Thanks again to both of you. Probably the best forum experience ever. Good advice and a potential to help the masses!!
