My HR20-700 has been doing all of this for months. Signal strengths are all in the high 80's/low 90's. It's just like everyone stated on here, choppy audio/video on DVR playback. I have the worst problems when watching a program that is still recording (say, I miss the first 10-15 min). After fast forwarding thru commercials, there comes a point where I catch up to being live. This is where the majority of the choppiness occurs. I usually have to go back 10-15 sec to correct some of it (not all). SUPER SLOW response time on anything with the remote (push 2-0-7 to go to ESPN News and it can take up to 20 sec for each # to come up on the screen, then another 20 sec to actually change to that channel). It comes and goes, like most others have stated. It will do this for a day or so, then I won't have any problems with it for 2-3 days then problems again right after that. My last effort (at the request of the technician I was speaking to over the phone) was to completely reformat the hard drive. It seemed to go faster for awhile after this was complete, but that night it went right back to being unresponsive. On top of all that, my HDD is very, very loud. Sometimes it spins when it's off and I have to unplug it to give it a rest!
