    Hi greg,
    If I'm not mistaken, I don't think you want to be running any cables through that surge protector. If you haven't already, try bypassing the protector to see if the problem goes away. Something to try anyway if you haven't already. The possible answer to why it's always Tuner 1 for you is if the voltage in the surge protector is interfering with the voltage range of Tuner 1. Just a thought.

    Bypassing my power filter and plugging my sat cables directly into the HR20 was the second thing I did after switching the BBCs all around. Same result.

    As I posted above, I did the same troubleshooting that Jon D described, and came up with the same results. I took the plunge and called D* for a replacement box. I got a refurb HR20-100 to replace my HR20-700. I also swapped out the BBC's since they included them in the box. So far after 48 hrs, no pixelation on any channels, and no other problems to report with the box. The HD even looks a little more crisp with this box than the last one. The only drawback to the whole situation was having to rebuild all the SL's, and having to pay for the shipping costs

    D* made you pay shipping on their defective, leased equipment? That's just wrong.

    Another interesting thought. My receiver is a HR20-700. How about you other guys? raz175 got a HR20-100 and the problems, at least so far, have been resolved. The 3 digit suffix refers to the manufacturer, correct?

    If someone were to run the lines through a surge protector, is there a brand or a specific spec on the surge protector to look for so as this would not be an issue if this is the cause?

    I agree, that's a crock

    sorry - that i'm not aware of. i've just read pretty consistently here that you don't want to be running any SAT cables through the protector. Maybe they're more designed for cable? or cable internet? not sure.

    The main reason people have problems with some of the surge protectors is the cable passthrough frequency range. Many of the cheaper brands pass through filter circuitry may not extend far enough to adequately cover the Ka/Ku bands. There are devices made for DSS protection which covers all the frequency ranges and DC voltages. An example can be found here; hyperlinktech.com/web/al-ffff.php. (Sorry, can't post the whole link, I don't have enough posts yet)

    And yes, it blows that D* makes you pay for the shipping costs on their defective equipment. Unless you want to pay $5.99 a month for the protection plan, then it's free.

    I am a new owner of an HR21-700 as of today. No problems at first, but after half a day I have a pattern of pixelation. It appears as a pattern if dots in a rectangular pattern 3 dots across and 4 dots down. Is this the kind of thing others are seeing?

    Bike Effects - if you're seeing this on the science channel, join the club (I think it's a small club, but it's definitely a club). The pixellation we are seeing is more like rain fade where portions of the image turn into random colored blocks. Sort of looks like olden days of real player video on the computer when it had a buffer problem.

    For the rest - I got my brand new shiny BBCs in yesterday! Unfortunately, no effect (like others suspected). I'm still going to wait for the next software update and pray something wonderful happens. But now I think I'll buy a set-top dvd burner and get it in the ready mode.

    I know this has been discussed a number of times, but if there was just a way to use something like a USB thumb drive to back up all of my settings, I wouldn't give a care if I asked for a new box every day. I guess that fantasy really only works if you have the protection plan.

    I found this surge protector on costco's site. It specifically mentions that the coaxial inputs are rated for 2.4 GHz.

    I'm on my second brand new HR21 as of 2 days ago, due to constant 771 message on tuner 1 on the first one. So far, so good, but did notice pixelating last night, but we were getting pretty hard rain, but noticed some today with clear skies, so hopefully this isn't another lemon HR21.

    I started to have some pixelation on one of my HR20-700's about one month ago. I started to troubleshoot and determined the intermittant pixelation was only occuring on tuner one. Protection plan customer service decided to send me a replacement tuner. After talking to them, I realized that the temperature was at 129 degrees (I had never seen it over 127). Pixelation never seemed to occur with the temp lower than 127. After a reset, it would take a while for pixelation to begin (this make sense since the hard drive is off during reset).

    I bought a laptop cooler and placed it on top of the tuner. Now the temp is stable at 113 and there is no pixelation!

    Meanwhile, the new tuner is coming tomorrow.

    That's very interesting. I noticed back when the H20-600 first came out that my problems with it were heat-related and corrected by a laptop cooler. Since that time I've put a laptop cooler on all my DirecTV receivers of any kind, and I've never had the first problem with any of them. Although it has been stated elsewhere on this forum that the HR20-700 is designed to run at 125+ degrees and not to worry about it (the -100's are cooled differently and run cooler), perhaps others who are having -700 problems should try cooling them. Mine run around 100-105. I use upside down Targus PA248's.

    Upside down in what sense? You have it sitting upside down on top of the hr20 or...?

    Correct, and plugged in to the USB jack on the back of the receiver.

    I like this. I never thought about temperature. I'll pick a PA248 and try it out.

    I am having a very similar problem on my HR20-700S. When both tuners are on Meg 2 channels, either recording or just tuned in, tuner 2 experiences very brief (fraction of a second) audio drops followed by very brief minor pixelation.

    For folks that have requested new boxes, has the new box solved the problem?

    Thanks

    I use to suffer from horrible pixelation on recordings as well. What really reduced it was adding a esata hard drive. That reduced it by 70%. We had also recently replaced our 10-250 in the bedroom, so we now had 2 hr20-700's. I swapped that with the downstairs system, and that took care of any other problems.

    The high def channels still seem to suffer from "rain fade" issues more than standard def, though. We were watching "Deck the Halls" Saturday night, and there were plenty of breakups, and we were watching it live.

    Scott, I had D* replace my HR20-700 a little over a week ago. I was sent a refurbed HR20-100, and so far it's been rock solid. It was on pretty much constantly all last week (I was home sick with the flu), so I was checking for any problems. If you haven't done so, you may want to follow the troubleshooting steps listed earlier in this thread. This will narrow the problem down, so if it's definitely the box, when you call D* for a replacement, and tell them what you have done, getting a replacement is a lot less painful.
