Yea, I guess it comes down to the HD thru DirecTV. If I am going to redo my whole system and spend the $ and time on Sage, I would want it to be a complete solution. Yes, I do get the major networks on OTA HD, but like you said, if I want to record other HD content (and there is alot coming) I need to be able to record it from D*. A HD DVR, like an HR20 is an option but then you get into centralization, matrix switches, etc to have it available. So I guess to make it a complete solution I need a D* tuner card that will work in Sage at least for the HD content, but still it would be nice to just have a few of them for all content and eliminate separate receivers, etc.
On a related note, there is one thing that kills me about DirectDVR/Tivo that I'm wondering about Sage. If I have a season pass for a particular show, say it records Sunday at 10PM. Many times a football game will run long and push back other programming, up to an hour sometimes. I have missed more than one show because D* guide doesn't update and I wind up recording the show previous to the one I want. So, how does the guide work in Sage? Is it updated more realtime so changes/delays in programming will be reflected? It just kills me when you are following a series and one in the middle is missed, and it is not duplicated anywhere else.
