    I've been having an issue since June where the local channels will pixelate at random for no reason. Weather is fair. No clouds or storms anywhere near. My current software is 0x740. Since getting this version last week the pixelation has been worse. I've got 20 instances in the first hour of Americas Go Talent.

    Now, I've been in communication with Directv and have now been assigned a case and a case manager to follow me through the process. My issue has also been forwarded to the engineering dept because no over the phone or service call has fixed the issue.

    I'm posting to see if others have the problem. If so I'm urge you to call tech support. I've asked several tech support agents if they have heard if this issue and they all seem genuine when they say no. Now, I've read several posts on here of people having the issue. So, post your issue here, but to get things fixed, Directv is telling me the need to have people call and open lines of communication so they can follow it! So people, if you have problems, call and start communication!

    I've posted a video as well for those of you who are Directv tech or engineers so you can see what's going on. Keep in mind, it's on the LOCALS ONLY.

    This is entirely possible; in fact, I have seen it happen in my market.

    There is a local pickup antenna or fiber hub for every local market, sometimes a combination of both. At that pickup point the locals are muxed together (subs often demuxed out) and the resulting single MPTS stream is fibered back to the DTV uplink center, where they demux, turn them around and pump them into the spotbeam uplink HPA. This means that from the pickup point to the uplink center is a common path with the potential for being a single point of failure. That is how the locals can have a common issue but the other channels can still be OK.

    It is usually fixed by a quick reboot of the mux or whatever other electronics are in the path, but the tricky part (and the part that takes time) is getting someone to actually do this, which only happens if folks complain enough.
