Mark, to tell you the truth, the only reason I even run Windows on the PVR is for the expanded support of hardware by SageTV. Once the system has been set up it's (the configuration) not something I really want to go back and play with.

I have some future plans for the PVR as far as capture devices go, so I'm going to look into Sage's Linux support on that end as well as power management (search forums and put in a question with their developers).
