Going to be using it with SageTV (does require Windows Media Center installed on the SageTV machine). Worst case (i.e., Google kills off SageTV), the tuner is compatible with MythTV and some other platforms. I pay for a dedicated cablebox now, and my cable company keeps screwing around with it, to the point that my USB-UIRT doesn't always work right, tuning into the wrong channel
This would take the place of 3 cable boxes, while being able to record the HD versions of these commercial channels.
