I have a HD ready Sony Flat screen TV, and would like to get HD. The TV does not have a built in receiver. Direct TV has offered me a HD DVR for $199 with a 2 year contract. I presently have a Tivo DVR unit which I like and have had no problem with the unit. I would like for someone to advise me on what they think about the Direct TV's HD DVR they are selling. I read somewhere that the Direct TV's HD DVR unit is not as good as the Tivo DVR. I am new at this so hopefully I made myself clear. I also would like to know what does one mean when they list HD DVR POS. Are they describing a particular unit? Thanks for all replys.
