We're all trying to help with a possible diagnosis.
Correct, picture is always 100% crystal clear.
Yes it occurs again with DVR at same exact spot.
DirecTV has sent a tech 5 times and he checked the ground and all good according to him. I'm no expert.
DirecTV has known about my issue for 3 months and they have known from day 1 that all TVs are affected.
The tech is case management certified. Take it for what's it worth.
DirecTV has stated they will NOT be sending a tech again. That was from a supervisor in case management.
I have no wall plates and I have no clue what a barrel connector is.
@Carl Spock That what is driving me crazy about this. And I'm not alone.
Others are reporting it at the DirecTV forums that litzdog911 linked to before.
The added information seems to reinforce that the source of your problem is NOT device-specific, rather, it is something in the "infrastructure" of your setup. It becomes a process-of-elimination road to the answer.
Since you indicated the techs were out multiple times...it's safe to assume that your Dish and multi-switches were checked one or more times as well.
The only other remaining variables are your audio system (which you indicate does not have this issue for Blu Ray sourced content) or your home cabling. The cabling is the only remaining item unique to the DirecTV source in contrast to a Blu Ray source. A simple short somewhere could corrupt the signal itself, but the audio and video would likely be affected.
Only the cables to and from the HD DVR to the audio system or audio system to the HDTV remain, and it appears those have been checked thoroughly.
So eliminating all of those possibilities based on your reports...I'm out of ideas at this point.
