    I was one of the people that mentioned this. I live west of an Air Force Base. When the military aircraft are north of my house there is no problem. When they fly to the south of my house I get pixilation. I don't think that it is the planes themselves, I believe that it is radio communications (either plane to plane or plane to base) although military radar is a possibility. The fighter jets chase each other around my house.

    I know just a little bit about radar systems. I'd absolutely think that could cause the problems you see. I don't see military planes here but I do see a lot of commercial flights to the SW. I was on a destroyer tied up in Norfolk when one of the new Radarmen turned on the surface search radar. We watched the...not sure what you call it...dish, I guess, rotate. That's something you never saw in port. Next thing we saw (I was on the signal bridge) was a truck with a rotating antenna of some sort pull next to the ship's gangplank. We had blanked out all reception in the area. Caught hell for that, the captain did. Yeah, radar can do some strange things.

    I started having issues watching this game last night too. I went into settings and did a reboot of all locations. Problem went away after the units came back up. Hs17/c61k

    I wanted to thank everyone for posting their experiences in this thread. One day we will figure out the cause of it. I just don't have the patience to get a tech out here... and he says... hey... there's nothing we can do... we changed everything out. And there still is a problem. That would really piss me off. The reason why I don't JUMP to get a tech out here... it will clear up for about 7 days with no issues.... then on one random day... Pixelation gets out of control.... and it won't stop. It just has a mind of it's own. Crazy.

    So wait you've NEVER had a tech out about this issue, but you've been posting about this for months??? Have one out, and tell him you've been told your symptoms sound like your LNB is going bad. It can't hurt to replace the LNB, and intermittent pixelation or 771s that come and go is basically the main symptom of a failing LNB.

    A bad LNB isn't the only potential cause of pixelation but it is the most likely cause. If replacing it doesn't fix the problem no harm done and at least you can rule that out and are no worse off than you are now.

    Thanks for the post. The system was installed probably in 2014. A new LNB... coax cable.... power source.... was installed in 2016 to fix an audio drop out issue.... prior to the pixelation problem. Once they installed all of the new updates in 2016... it never fixed the audio drop outs.... Just using the main Genie... and an HR-24 receiver... fixed the audio drop out issue. DirecTV reps are just clueless in diagnosing the situation. It's like you have to take a little here... and a little there from people who post... and other websites.... to figure out what's going on.

    I have plenty of discounts from DirecTV and freebies for the next 11 months... basically I just post for reference.... and hoping one day someone posts in this thread... HEY I FINALLY HAVE A FIX FOR YOUR ISSUE. But as a few posters have said... it looks like a Regional Issue.

    If I get really annoyed... I might have them send out a tech. But I feel like it's not going to work.

    LNBs don't only fail due to age, some are just a little off spec and fail rather quickly. FWIW, calling it "failure" is perhaps a misnomer. What happens almost all the time should be more accurately called frequency drift, though that is a type of failure.

    Even Directv's modern "digital SWM" LNBs like the reverse band 3DR/5DR models everyone gets today are still analog in the front end, and rely on DROs (dialectic resonant oscillator) to generate mixer frequencies to downconvert the very high frequencies satellite signals are broadcast at.

    DROs can have their frequencies drift due to vibration or heating/cooling cycles, which is why it is often intermittent. When the frequencies the DROs generate are off, the frequencies the receiver's tuner sees are off. If they are too far off from the standard frequency for a given transponder that the receiver is expecting, the receiver's tuner struggles. That leads to pixelation, or worse, 771s - and it might not happen on every receiver (i.e. it is possible if the frequency is just a little bit off that one model is OK but another pixelates or gets 771s)

    So IMHO just because you had your LNB replaced in 2016 is no reason to believe replacing your LNB won't fix the problem. Especially since you say the pixelation appeared after that 2016 LNB replacement. And like I said, if it doesn't fix the problem you are no worse off than you are today.

    Too bad Directv doesn't use PLLs in their LNBs, they cost more than DROs but are nearly immune to this sort of issue. But I guess they ran the numbers long ago and it costs them less to have installers replacing LNBs that fail rather than making ones much less likely to fail. I've never seen the inside of a 3DR/5DR LNB so I guess it is possible they switched (since they'd already need a much lower frequency PLL for the DSWM chip) but knowing how they work I really doubt it...

    This is a very interesting thread and I have something new to add.

    I have two receivers at home; an HR44/700 (Genie) in the living room and an HR24/200 in the office. I have the "Whole House" thing as well as a wireless receiver and one of those really small wired receivers, so 4 receivers in all although only two have the ability to hold recordings.

    This morning, I decided to watch National Treasure again. It was recorded on the HR44 and I had an opportunity to watch some of it last week. So, from my office, I chose NT on the List and hit Resume. It started, but was pixilated. I didn't remember this part being pixilated before so I fast forwarded a few min. Pixilated. I rewound and it was pixilated. The whole thing was pixilated.

    I went to the HR44 and hit the red reset button and waited "a few seconds". When it was through, I brought up the movie again and zero pixilation throughout the movie. Zero pixilation.

    Now I have to rethink my past pixilation experiences as I watch mostly recorded shows and not so much live shows.

    I also wonder if I can pull out the internal HD from the HR44 and connect it to my Windows 10 desktop machine along with a BSN 3-6 Gig HD and clone the internal to the larger HD. Then, install the larger HD into the HR44. Has anyone tried that?

    Back to morning brew . . .

    You're thinking it's the HDD that caused the problem? I don't see that.

    I dunno, which is why I brought up the question about Cloning. Another member, DaRef, Posted in June last year that he attached an external drive and that it solved the issue (post 21 of this thread). I thought it may have been a short-term fix but he posted again in Feb this year stating all his issues went away. I would think if it was something other than the HD, the freezing/pixilation would have returned in that 8 months.

    I have quite a bit of shows/movies on the HR44 that I don't want to lose, but I don't want to "shut down, disconnect an external drive, reboot and wait 'just a few seconds' " just to watch the old shows. I would rather Clone and replace the original HD. Has anyone tried this? Someone mentioned a Purple HD is expensive. In the eye of the beholder, I guess. Amazon 6GB Purple for <$200.

    Back to my morning brew . . .

    Yup, for a 6TB drive (think that's what you meant) less than $200 is a decent price. For the Purple drive.

    I don't know if the HDD could cause your problem, I've never seen such an issue. But I would not be surprised if the HDD was at fault. I started using SSDs in docks about 8 months ago on my 44 and two 24s and have not seen one instance of pixelation since I installed them that I could blame on the drives. What I had were 3 HRs that were very slow and cranky along with a lot of pixelations and audio drops. That all went away immediately upon installing the SSDs on each HR. So, yeah, I now think most of the problems we see are caused by the HDDs. For years I blamed the software on all my problems and I was just plain wrong. I'll put a link in to the thread about the SSDs as soon as I post this.

    Okay, here's that link: What happens if I put a 1TB SSD in my HR44-700?
    What I think happens is the HDDs work great initially then slowly degrade but don't stop working. Once the degradation reaches a certain point the HR slows down noticeably and the pixies and audio drops begin. You run the built in diagnostics and everything comes up good but change that drive to a new one and the problems disappear. I don't think the diagnostics can "see" the level of degradation the HRs are at.

    If folks are power users and record damn near everything an SSD is not the answer at this time, too expensive. But for folks like me...I only record a few things, mostly sports, so capacity doesn't matter.

    Were I you, I'd try the Purple Surveillance WD HDD and see if it fixes your problem. I always recommend keeping any HDD no more than half full on a DVR. You will have fewer problems.

    I just wanted to update this thread...

    It seems the pixelation that I was experiencing for years has finally gone away on it's own. It's been about a month and a half since I noticed any type of odd interruptions.

    The last software on my H44/200 was Friday 5/10 at 4:21 AM. Software: 0x11b2

    I am crossing my fingers heading into August... and into football season that this holds. I've been waiting for it to pixelate and screw up... and it hasn't. This is unbelievable.

    Maybe it was sunspots :rolleyes:. I had the pixelation too and it has gone away for me as well.

    Was the update the only thing that changed?

    The only thing that I've noticed was the possible software update. I didn't do it on my own....

    Also, no service techs.... no phone calls to DirecTV for at least maybe 6 months? So everything was done on it's own. Maybe the technical engineers finally figure it out?

    Just wanted to make a post... so others can review. Hope it holds.

    If the problem doesn't pop back up consider yourself lucky. Hope that happens. If not, come back.

    I am still having pixelation and audio judder especially on some sports channels. It happens for me on ESPN, & Some of the RSN’s. I have an H25/500 HD only receiver. Not a Genie DVR.

    Do you watch YES at all? I used to complain about the pixies and audio drops on YES and then I put SSDs on my HRs and all that went away. It wasn't the broadcast, it was the HDDs. Doesn't help you much but at least you now know that someone that watches YES and ESPN a lot never sees pixies or audio drops on those channels. It's not the broadcast in my case. I have no idea why a receiver would do such a thing. Perhaps replacing it would solve the problem?

    I was so sure YES caused all my problems and I was so wrong.

    He says he is watching on an H25 receiver, so it can't be DVR related.
