Media Center is the latest 24.0.41, sorry I only put the last two numbers in my post. yes I rebooted and also updated the video drivers. it is an AMD quad core with 16 gigs of RAM and a SSD for the boot drive. I have WinTV dual tuner cards (total of four tuners) and also found and installed updated drivers for them. I have plenty of space on the drive that the TV records to. It acts like windows is blocking access to the video card. I have not tried turning off the hardware accel yet but I have done that in the past and the picture looks quite poor. oh I am using the HDMI out, passing through a receiver to drive my surround then it is going to the TV.
