Hi, I have been doing google and here for a possible solution to use the AM-21 on a PC. When I plug it into the usb port of my Win 7 pc it installs the usb protion but says there are no Direct TV USB tuner 1 & 2 drivers. Sooo has anyone messed with this, and come up with a solution. I would like to take this on the road with me to get locals.. This is a $50 box and lots less expensive than some of the other ATAS tuners. Thanks!!
