Hi there! I am new to AA1, and I am wondering if anyone has any experience with using an external TV tuner, such as Hauppauge 850 usb tuner ([URL]http://www.hauppauge.com/site/products/data_hvr850.html[/URL]) , with their AA1. Is there a way to install the software, and use the AA1 to view TV or as a PVR?
