It's not. And since Pinnacle isn't producing TV sticks anymore it's a pain. I contacted the group maintaining legacy support. They're responsive but useless.
For instance: there are no Windows 7 x64 bit drivers. There are beta Vista x64 bit drivers. The drivers are on the TV stick itself and you need an update utility to replace them with the beta drivers.
Contacted them about how to do it. "He" said "run the setup app in the zip file." Well, the only executable in the zip file is a monitoring tray app. I replied with that data and showed the contents of the folder to them.
He said, "yeah, run that."
Great. Didn't do squat.
I bought the Liquid Nero Tivo thingy to try. It was on Woot for $35 last week.
