No MPEG4 or Severe Pixelation on All MPEG4 Channels, but SD/MPEG2 is OK

    Anyone else having these problems?

    I can get to any SD channel or any HD MPEG2 channels, but when I try to go to any MPEG4 channel, I ether get a gray screen and no audio, or sever pixelation.

    I'm in the NY DMA, so I don't know if this a regional issue or not.

    I had these problems on and off yesterday afternoon, so this is Day 2 for me.

    What are you signals like on 99/103.

    Have you tried a restart.

    Earl, My HR20 restarted on its own about 15 minutes before I opened this thread.

    The signals on 99(b) are:

    Tuner 1: 1=100, 2=100, 3=98, 4=100, 5=100, 6=100
    Tuner 2: 1=100, 2=100, 3=97, 4=100, 5=99, 6=100

    The signals on 103(a) are:

    Tuner 1: 1=98, 2=80, 3=0, 4=99, 5=96, 6=83 and 17=0
    Tuner 2: 1=98, 2=80, 3=0, 4=99, 5=95, 6=84 and 17=0

    I'm not sure what these should be (whether the 0 is appropriate for my location), but I just got off the phone with Tech Support and she told me that looking at signal strength wouldn't tell her anything. She says the problem is most likely my dish, because MPEG4 comes from different sats, so I have a service call scheduled for Tuesday evening, between 1 and 5 PM.

    Anything else I can look at?

    I'm not Earl [Duh] but those numbers are great. Your dish is "nailed" to the SATs.

    Your MPEG-4 HD locals come from a couple of transponders on the 99 satellite. 103 has spotbeams for other cities, the signals you see are not for you so their strength is not relevant.
    Your 99 signals are excellent so whatever is your problem it is not dish alignment or the LNBs.

    I remember being amazed at my signal strength after the new slimline dish was installed in March, because on the old 3-LNB dish, I had only a couple transponders in the 90's. This installer knew what he was doing; his aim is right on. :up:

    This is why I'm so surprised I'm suddenly having a problem... We've even had rainstorms recently where I didn't lose signal.

    The CSR asked if I had the BBCs installed, and I do, so what could be a likely problem here? What would a tech do when he shows up Tuesday?

    Try taking the BBCs off and see if that helps. You may have some bad ones.

    I have read some other threads about NBC in NY having some issues so perhaps it's not just you. But try removing the BBCs. If that solves the problem then get them replaced. They aren't needed now but will be when the new sats go up.

    Had the same problem with a HR20-700. Problem was with on of the two tuners. Problem only occurred on HD locals in MPEG4.

    I received a new 100s this week

    Well, I took the BBCs off early this afternoon and still had pixelation on the MPEG4 channels. I left for several hours, and as of now, with no BBCs on the lines, the MPEG4 channels are coming in fine.

    Hopefully the installer will just have some spares on the truck, because it seems like a simple thing to replace them as a precaution.

    I've been having the same problem with my HR20-700 since a few hours after the installer left 2 weeks ago. All my signal strengths look good (high 90s-100 on the old sats, low 90s on the transponders I get on 99/103). I haven't had the opportunity to have a service tech come out to look at it yet since I've been on vacation the past week. It looks like this may be a more widespread problem. Gonna try your fix when I get home today, but I'm interested to see what they do on your service call before I schedule one.

    I haven't seen any problems since I took off the BBCs, so I'll fill you in tomorrow after the technician checks everything else. The BBCs I had are less than two months old, but I guess anything can "break" without warning...

    MPEG is the encoding algorithm used to "digitize" the picture. MPEG-2 is an older version & MPEG-4 is the newer [which make the file size smaller than the older version].

    The technician left a little while ago. It turned out to be the same guy who installed y Slimline dish and the HR20 in March, and he got a kick out of hearing that the DBSTalk posters liked his aim! :)

    He said a lot of people had problems with HD channels 4 and 5 over the weekend, so he blamed DirecTV for playing with the signals, but I told him I also had problems on YES-HD, so he went ahead and fixed the BBCs anyway.

    I had put my BBCs back on the HR20 this morning and everything has been good all day, so maybe it was a "fluke" that I had problems over the weekend.

    The tech ended up changing the jumpers in each BBC and putting a new lead between each BBC and each SAT-IN connector on the back of the HR20. I didn't even know there were jumpers in the BBC, but he just flipped the top off and was done in 10 minutes total, including all of our chatting. Everything is running fine with the "fixed" BBCs on.

    One thing I noticed is that one of the old leads from the BBC to the SAT input had exposed copper wire, right after the rubber closest to the BBC side. Who knows if this was causing the problem, but I'm just happy it's bacck to normal.

    By the way, he's the same tech that in March told me DirecTV would be flipping all of the new HD channels on this September, and he's sticking to that. :)

    Guess what ... I have again lost all MPEG4 HD channels. It started at 6:16 PM Eastern with pixelation, and now is just gray screen on any MPEG4 HD channel.

    :(

    I'll be taking the BBCs off again to see if that makes any difference ...

    Have you tried to by pass the multi-switch? Maybe the multi-switch went bad or is going bad.

    OK, some progress ... I had been jumping around on all the MPEG4 HD channels, but obviously only one tuner was affected as I changed channels. I decided to record from two SD channels to force the tuners off an MPEG4 transponder, and then canceled the recordings. I went back to the HD MPEG4 channels, and they're both fine now. So... is this significant or just coincidence?

    The next time I see the problems on the MPEG4 channels, I'll bypass the multiswitch and see if that helps. Thanks for the suggestion ...
