I'm sorry you are having problems with your HR21-700, but I wanted to relate my experience. I have been following this forum for as long as it has existed, so I read about all the problems being reported on the HR2x boxes. The forum has a lot of people who speculate as to what causes these problems, so when I got my two HR21-700s last February I wanted everything to be as perfect as possible.
The problems mostly seem to be caused by:
1. Bad dish alignment
2. Out of spec RG6 cable
3. RG6 cables not all exactly the same length
4. Poor installation of RG6 cable ends
5. Heat because of poor ventilation
The DirecTV installer would not replace my RG6 cable even though they require cable that is rated at 2.5 Ghz or greater and mine was rated at 1 Ghz. So I went to a local cable supply store and purchased 150 feet of dual RG6 cable that had DirecTV stamped on the cable and is rated at 3.0 Ghz. I also purchased a cable end compression tool, a cable stripper and a package of 25 RG6 compression ends. I replaced all the cable myself making sure all the cable lengths were identical.
I also know that heat rises and since the HR21-700 is vented out of the left side, I mounted both of my HR21s to a wall in my wiring closet with the left side up.
Since then I have never had a blank or missed recording and never had a 771 error. The only problem I can see with my HR21s is I don't think the trick play is as smooth or as quick as my HR10-250.
The cable cost me $.20 per foot, the compression tool was about $30 and the cable ends were about $1 each, so I have invested about $75 to make everything as good as possible and my systems work nearly perfectly.
I don't know which of the 5 items I listed may cause problems, but I addressed them all and I don't have problems.
I can still get OTA HD and D* SD with my TIVO HR10-250. I use the HR21 mostly for HD movies. I would not recommend the HR21 to a friend as a "high end" DVR until the the software is stable and the feature set is upgraded.[/QUOTE]
Thanks for the lists of potential alternate causes.
The first DIRECTV system I personally installed in my house was in 1995. I bought it for $800. I know do know the difference between RG59 and RG6. I have used a UPS at least since my UlitimateTV. Sounding old here.
I am with you on some of those, but explain to me the cables of equal length. Are you talking about equal length to ALL receivers or equal length to the 2 RG6s at EACH receiver?
Either way, one of my SD DirecTivos (HDVR2 ) replaced a old DIRECTV tuner. The old unit old had one tuner so 1 RG6. I ran the RG6 the long way under the house. When I upgraded my living room DVR I had the installer move the DirecTivo to that location. He had to run a second RG6 to get the second tuner working. He refused to go under the house and ran the cable along the roof gutter and through the wall. The cable run is probably about 30' shorter with one less junction. That unit has never had ANY reception problems.
The shorter the cable the better. I am not running a 100' run to a box that is 20' from the dish. With cable runs use the shortest cable possible for the least signal loss.
I'm seeing an internal temp usually around 113'. What internal temp are you get by hanging it on the wall?
I am curious to see.
Also, many electronics are required to only be mounted in a certain manor. Have you seen something from the manufacturer recommending mounting your unit in that orientation?
Thanks again for the ideas but I am also trying to avoid red herrings.
You got me to look at my signal strength. And something is going on. Tuner 1 is at 0 for everything and tuner 2 is mostly at 60%. I'm guessing the LNB or multiswitch is going bad. Hmmm...
As for the remote responsiveness, I am certain this is related to the last NR software update.
