How many times did this occur tonight just that one time? BTW from 27' away that thumbnail in your post looks great on a 15" monitor, perhaps this is how the encoders are being "tuned" by dish.
 
saw it more than once. When I tried to pause the clip I missed it the 1st time and had to re-wind and paused it right on target, like I said, it was about a 1/2 second of pixel/blur muck.
 
Again, that is comparing how bit rate affects PQ. No one disputes that. Now show me something like that with signal strength to back up your claim.

The coupling between BER and SNR is a logical one. In general, the higher the SNR, the fewer the errors in the channel transmission; or simply stated, as the SNR increases, the BER decreases. Conversely, as the SNR decreases, the BER will increase, at which point the communications channel typically reduces the data rate (making each bit a little longer) in an attempt to reduce the number of errors in the transmission.
AND
Notice that as the SNR decreases, there is a graceful degradation, or roll-off, in channel performance. For example, as a 5.8 GHz signal's SNR is degraded,
the channel will tend to remain operational, albeit at a reduced data rate.

Nope, you missed again.

Show real world examples...screen captures of the same program with high and low signal levels that shows a PQ difference.
That is something that you will not see as proof. Anyone that has tuned in a sat system, or even a simple OTA antenna knows this.

What you might get is another 5 or 6 paragraph technical explanation of why he must be right, and it may or may not be related to the question you asked.
 
I really think technology is spoiling us all. My pictures on the 55 are always clear but sometimes they are clearer than others.Not sure why, but not worth the effort to find out.
But along the same lines, I can't watch a SD show or even go to the theater anymore.
I am always comparing the images and my TV is winning hands down.
 
Diminishing returns

What you are not realizing is there is a point of diminishing returns on that BER to SNR. This is accomplished well before there is any loss of signal. If you have signal level of say 30 then it will be as good as a signal level of more than 50. As I said the lowest signals I have is in the 50's and some of the signals I get are in the mid 80's. I can see no difference in the pq of those that have 85 over those that are in the 50's. Your waterfall as you like to call it is a very fast drop off. Which up until recently was know as the cliff effect. Well the drop off may not be a straight 90 degree drop off but even your graphs are show something like a a sharp curve then an almost straight drop after the "knee". You just don't get that you are trying to push a belief that true in the "old" days and it just doens' hold up that well anymore. I wish you would get a clue that we are not going to bite on the idea that you keep trying to shove down our throats. Your proof just doesn't hold up.

You bolded it, so you apparently think it's key. We have transmitters and receivers. The transmitter at Dish sends a signal to the receiver on the satellite, the satellite then transmits that signal to your receiver at home. Disagree so far?

Now, when the signal is encapsulated for transmission, there's certain parameters used (FEC & Data rate among them). The receiver then uses those parameters to see the signal. Now, according to you (what YOU highlighted in bold), the data rate changes with a lower signal to noise ratio. Now, as this transmission is going across the country, to millions(?) of receivers, can you explain how ONE receiver with a bad signal will somehow indicate to the transmitter the data rate needs to be changed? Keep in mind ALL the other receivers across the country would then have to change THEIR data rates to match what is transmitted.
 
Even the best looking BD movie will look bad at 1 foot.


That is totally not true. Blu-ray quality at any distance is noticeable and looks fantastic. Blu-ray completely kills Dish PQ (obviously, it should since the compression is much better and it is 1080p). Even Cox cable is clearly better than Dish. I did a side by side comparison while I still had both hooked up. Again, some channels are better than others. However, I should not be able to see compression artifacts when I am sitting over 10 feet away from my t.v...which is exactly what I see with Dish.

same thing I noticed except TWC not Cox

At 10 feet I never see any compression artifacts on Dish unless they are showing a program that itself has a bad transfer. Maybe you need a better set?

And at 1 foot, the best BD will indeed have noise and compression artifacts on any television set. You're just complaining to be an annoying voice. :up
