My service call is scheduled between 1 and 4 pm today to try and get my MPEG-4's back. I'm betting the tech shows up after 6pm, and more likely after dark. This way, he can protest when I tell him to climb up on the roof to check the LNB and connections. If it's the same guy who initially "installed" my system, I will go nuts. I'm already anticipating the "there are trees blocking your reception...call me when you cut them down" line.


It may not be the same guy. Atleast the company that does the installs in my area have a few TECHS and they are the only ones that go out for service calls.

I have an installer coming back out next week. I'm getting very low signals on the 99 and 103. I tried the fine tuning dials on the dish myself and that only made the signals worse. For those of you that said it is simple to "re-aim" the dish, how did you do it? I'm in the 90's on 110 and 119, and in the upper 80's on the 101. I think my whole dish needs a realignment. This is the third time in 6 weeks that somebody has had to come out.

Tech that came out today replaced my old 5lnb dish with newer slimline dish. I was having the pixelization problems while he was here so I was thankful for that.
He said 99% of the time it is the dish, said the slimline has less problems, and its the first thing he will replace on a service call with this type of issue because most often he will not end up returning to that customers location.
Since it was replaced I have yet to see the problem, but its only a few hours into it. I'll post back if it shows up again.

You really need to know [or have an understanding of] how it works. What I read in you postings is you've got the western SAT aligned well, but not the eastern. The mast needs to be plumb, and then "I'd" look at the tilt which is to balance the east/west SATs. Of course changing this balance might [would] need to have either the EL or AZ [or both] to be readjusted. It truly is a balancing act, as any adjustment will affect the other SATs, so you need to know the "geometry" of the adjustments & how it relates to the dish pointing to all five locations.

I was able to fix it this afternoon. I had to move the dish a bit more to the west and now i'm getting signals in the 90's on all 5 sats!

I have finally isolated my problem after discussing my situation with a coworker. One of my tuners is obviously broken when it comes to displaying MPEG-4 channels. In order to test it I did the following:

1. Tune around until you find a good MPEG-4 channel.
2. Press record to lock that tuner on that channel.
3. Tune to your other MPEG-4 channels. None of them should work (they all experience the problem).
4. Press record on one of the channels that is not working properly.
5. Return to the good channel you started the first recording on and stop that recording.
6. Tune to all of your MPEG-4 channels other than the one you are recording on the bad tuner. All of them should appear correctly (no glitches).

To further test the problem, I switched the input cables to make sure there was no problem with the line. The channel I was watching on the good tuner came back properly as before. Repeat the procedure listed above if you wish to completely test it. I'm going to be calling DIRECTV to get a replacement DVR.

If the Dish isn't dithered properly than you may have more of one bird than another signal level on meter is not the greatest. I use my birdog meter to get my dishes set.

Just wanted to let everyone know after watching HD locals all weekend, I have not seen the problem again since the dish was replaced. Must have been a bad LNB on old dish, or as the tech said, condensation problems.
