What are the different UI modes (PVR / TV Viewer) for? What can/can't you do in each mode?
My guess would be that Tv Viewer mode will launch directly into live TV as PVR mode will launch to the main menu. But that's just a guess.
yeah, sub put that mode in for people who just want to watch TV on a desktop PC without all the PVR functions. he talked about it briefly in some thread around the time NPVR first released.
