You asked early on about media center options: I have purchased a new Tivo Premier from ebay and it also supports Netflix, YouTube, WebVideos (Pandora, Rhapsody, list goes on) Been recording shows in HD beauty with it since I started this adventure. This replaced our own Directv setup and DVR, we had TiVo in the past and it's UI is unmatched.
I paired this with a new Vizio LED w/ internet apps (since I was saving a nice chunky $100/mo now
) and I have yet to be at a loss for tons of shows to entertain us.
I think the previous posters (and you, yourself) got your equipment nicely dialed in.
