let me answer that, first i dont like live tv, too many disturbances, dogs barking, horns blaring, people asking questions phone ringing etc. i love being able to run it back and watch listen to it again
now when jen was around she demanded her own receiver.. i am a neat freak deleting old stuff, she prefered to fill the hard drive and let the old stuff just sit there. she had a thing for cooking shows, but rarely cooked. she put in over 75 timers once and crashed a 721.
so it was better we each had our own 722, which were kept in single mode on the primary tv, and a 625 for kitchen bedroom, shop etc. for awhile i had a feed to my shed and used it as a shop.
This kinda carried over to my roomate, it was just easier, and from time to time me and jen had house guests once they stayed 8 months
.... at the time they had no where else to go.....
so 3 receivers were fine at 5 bucks or 7 bucks each but were insane at $17 each
DVR is like getting a infection it spreads...
My roomate has asked when I am getting her a TIVO too....
She liked having her own box....
For now its my tivo and a comcast digital box with on demand, plus netflix on tivo.....
