In good fairness (being a Canuck), I haven't attempted to use SageTV since it failed to support the HDHomeRun on Windows when I last tried it, two years ago (EDIT, yes, on Windows -- the Linux version isn't available for h/w vetting without upfront payment).

It also seemed to be missing any kind of power management interface (auto suspend/shutdown between recordings) for Linux, and nobody at SageTV or in the forums was willing to suggest otherwise. Total lack of knowledge and support.

That's what pushed me over to Myth. The current Mythbuntu distro was as simple to install as SageTV was back then, though that's another temporally unfair comparison.

Cheers
