I currently have a Sony SAT-T60 DirecTiVo that I've had for years and absolutely love it! I'm planning on going to HiDef though and have a few questions.... From everything I've read, if I want all the HiDef channels, my only choice is the HR20 DirecTV DVR. From all the reading I've done on DBSTalk.com and TiVoCommunity.com, the HR20s had a lot of problems in the beginning, but now are fairly stable. Is this a correct statement? Is TiVo going to come out with a unit that will get all the new HiDef channels that DirecTV will have or are we just stuck with the DirecTV DVR? If TiVo is coming out with one, is there an ETA on it? Can another hard drive be added to the HR20 in order to increase the recording time more than 30 hours in HiDef? If I end up with one of the HR20 "lemons", how well is DirecTV at replacing them? Is it true DirecTV locks you into a 2 yr. commitment w/ the HR20? I've had a hard time finding what have outputs on the back of the HR20, can someone help me out with this and if possible provide a picture of the back of the unit? Thanks in advance!
