How did moving fix my bad PQ problems with Minneapolis Locals?

I thought I'd report back on an issue I was having with my Minneapolis Locals last year. Here is a link to the original thread which is now locked ...

I continued to encounter picture quality problems with my local MPEG4 locals. In June, Directv replaced my old AT9 dish with a new Slimline dish. This had no effect on the picture quality. Again, its worth noting, I had all signals in the mid-upper 90's so this was not a signal breakup problem. In a nutshell, at times, the MPEG4 locals had the appearance of a bad bit-starved web streaming video.

Around late November, I moved about 2 miles away to a new house. Directv installed a new SWMline dish. I now have a noticeably better picture on all of my MPEG4 locals making them pretty much indistiguishable from the OTA feeds. This is the same on all 3 of my HR20s.

My question is this: What changed? Did my move just happen to directly coincide with an upgrade to the Directv local MPEG4 encoders? If not, then what was causing my bad PQ at the old house? 6 bad BBCs??? Is the SWM better at converting the B-band signals?

Unless signal degrades below the threshold any signal that comes into the box is equal. BBC or not; 50s or 90s. And yes there is sure an engineer to be found to dispute me on this but to do it as drastic as you describe it wouldn't.

Cabling and switchgear likely changed for two items.

It is possible that there was a "leak" in your old cabling that new cabling put a stopper on. It is also possible that the multiswitch was not getting (cabling issue) or putting out (power issue or partial failure) a quality signal and the result was lots of errors but not enough to trigger a 771.

Reduced digital PQ can come from noise just as it did with analog and it isn't always chunks that come out. Sometimes, there is a more general error rate thing going on where the signal is consistently degraded.

I had my boxes upgraded recently to h-23's.. and my picture is much, much better.. I have a new slimline as well. but the picture is way better then my old boxes.
