The story is long and sad but suffice it to say we invested in DirecTV HD solution before we realized that we couldn't use our Series 2 **at all**. For whatever reason, my husband thought we'd be able to watch HD and SD thru the tivo, just not record in HD. OK - stop laughing - we blew it - but now we need to make some decisions going forward. Our current setup is to watch either HD live (no Tivo interface, no theatre sound) or our old Tivo set up with all the tivo benefits and 7 channel surround by switching sources (we use two DirecTv receivers, the old one and the new HD one). It's a kluge but we're stuck with it. I refuse to give up my tivo and my husband really likes the HD for sports. So, what to do now.... I was willing to invest the $400 to get the DirecTV HD DVR (and we'd both be happy) but now wondering how long it would be viable. After reading everything I could here, is it my imagination or is there a 100% chance that if we purchase the DirecTV HD DVR (w/ Tivo), that it **will** become obsolete when DirecTV starts broadcasting in a different format? Is that what all you DirecTV HD DVR owners are assuming? And do you have a backup plan? What are you planning to do when HD signals are no longer readable with the DirecTV HD DVR? Or am I missing something here? And can anyone give me a good idea how long you think it'll work? Are we talking fall 2006? In other words, before I throw that $400 away, I might be willing to risk it for a year's worth of HD tivo - but not if it'll be obsolete next month. Just need some numbers to figure out what to do. I really need simple mathmatics. It would be like "renting" a car - I'll 'rent' HD tivo but how many months do you think I'll get for $400? 2 months is way too expensive, but 12 months.... Might be worth it. any input would be appreciated.
