Well, i've been using the DirecTivo Series2 unit for a long time, and will continue for a bit longer....but the wife has given permission to upgrade the home theatre to HD/DVR. I have the basic OTA channels now through my Media Center PC. I've been reading the great info here....thanks to everyone who puts together these FAQ's....good stuff. With that said, I have a few questions outstanding: With all the reviews around the different HR21 "models" (700, 100, etc), I'm assuming when you call direcTV you don't get to choose.....question is, do you care? They all have the same features and capacities, right? Just look a little different on the inside? It appears there COULD be an opportunity to negotiate for free dish, and possibly lower priced DVR's.......with free installation. Use the "i've been a customer for a long time" approach coupled with "I'm shopping my HD options". Anyone else got a better trick? <g> I'll still have my DirecTivo Series 2 upstairs in the living room, but perhaps I can negotiate to get the second HR-21 .... we'll see. Lastly, I see people are expanding their HD Drive storage with eSATA drives...is this common? I think the standard drive probably will fit my needs...i'm not a packrat. Thanks for any thoughts! Dave.
