I have a Panasonic TH-50PX60U and have DirecTV HD programming (newly installed). The HD channels are pixalating during great weather (local are most frequent, but THTN also has problem; none on HD Discovery channel). Connections are HDMI, and optical between components and RG6 coax from sat receiever to dish. I have had technicians out three times and all wiring, LNB, and DirecTV receiver were replaced. Dish was checked for proper placement and interference. All connections (even interwire coax), cables checked for nicks or cuts. Problem does not occur on SDTV. Problem is not related to any activity (changing channels, input..). Anybody have any ideas?

I have the same problem. Mine seems to be limited to shows between 7:00 PM and 8:00 PM. DirecTV sends someone out to look at me funny.

DirecTV asked I keep a log -- this problem occurred at all times -- (I get up early), 5:30 AM, 6:10 AM... then in the evening. Most often on local channels, but on the movie channels as well. I read somewhere today that this is caused by station transmissions -- nothing anyone can do about it at this time.

After working 40 years as an engineer, I can report that the hardest problems to fix are the intermittent failures. How do you fix something that doesn

The last installer to service the problem actually did realign the dish and did manage to get readings of near 100 on some channels, but said that there needs to be a compromise to access all channels. The compromise is, as you suggest a loss of signal strength on other channels. I

The specs say that a 100-foot cable doesn

Thank you

If you put it outdoors then you have to waterproof the connections. The best place for a midline amp is closer to the dish than the receiver, but it should be at least 25 feet from the dish. If the total run is 50 feet or less then extra connectors in the run is not likely a problem. -Ken

The whole pixilating/ Directv thing really has me puzzled. I'm sure, as you say, it can be caused by improper aiming of the dish, but what I am finding leads me to think it's a source problem with the broadcaster or how D* handles that specific broadcast.

Most of the NBC/NHL HD games ranged from annoying to unwatchable. This has happened since last year and had gotten worse this year until a couple of weeks ago where it showed an improvement that put it back on last year's quality, where the audio drop outs far out numbered the video problems. Frequent inquires yielded mostly nothing, except a couple of techs saying that it was the fast action of the game that caused ther pixilazation problems. This made sense because it only happened during game action. I'm not sure why this would affect the audio also. Then again, NBC football this year had none of those same problems that hockey had.

I also have problems with specific programs on during prime time, like Boston Legal, which has lots of video problems. I was able to solve this problem by not watching it anymore, as the ultra liberal producers and writers used and ruined this otherwise fine show with great actors as a vehicle to shamelessly hammer home thier political point of view.

But I digress. Why would an ABC show at 10pm have problems that another earlier ABC show would not have? Desperate Housewives will "jump" once in a while, but nothing like Boston Legal.

So what causes this stuff? Is it content, like a fast moving NHL game? Time slot problem, as Boston Legal seems to be? Maybe too much over the top liberal content?:)

I couldn't agree more with the last comments on that ultra "liberal" Boston Legal. I've solved the problem. though. I had a DVD made with only Bill O'Reilly reruns. Now, besides the constant erection, I don't have to put up with any feelings but pride in the 'ol US of A! Praise the Lord!
