I figured I'd chime in here too, as I just replaced my RCA UTV with a new HD-DVR and a second HD receiver... My experience has been great so far - the tech that did the install did a great job - had to leave my old dish on the roof due to a wasp nest, but other than that, I can't complain. He used the old coax that ran through the outside wall, so no new holes in the wall, which was nice. The primary receiver/DVR is in my living room (which used to be the only place with DTV), and with a single coax run, I now have the same HD access in my family room because of SWiM - I still don't get all of the technical stuff on the new system (like the first poster, I really didn't follow the technology on this for a long time, since I didn't want to give up UTV), but it works great, plus I got whole home DVR, so the family room recvr can watch what is recorded on the living room DVR. This works great for us, we used to have 2 cable DVRs (one in each room), but you had to record it where you planned on watching it, which really limited the use of the second DVR. I was able to get the HR24 and H24 models, and I am very happy with the speed and ease of use, and it is amazing the number of new functions that they can add in 10 years! Since the regular season hasn't started yet, I can't know for sure how much I will miss picture-in-picture (I primarily used it for Sunday Ticket), but I think all of the other improvements have been worth it.
