It makes prime time shows like The Black List, L & O SVU, Chicago Fire and Chicago PD definitely enjoyable. That's when you are satisfied and know that your nice AVR was a good investment. I leave it at that.
I am trying to sort-of agree with you. I am telling you that it's a losing battle. Many broadcasts are flagged as DD 5.1 on my Denon but my ears tell me otherwise. The Hurricanes, Bobcats, anything on ACC Network, FS South, NESN, and many many many other channels show up as DD 5.1, but are not. I agree that Pro Logic is old but it's better than DD 2.0. I would like to use DD 5.1 but since the aforementioned broadcasters can't get it right, I gave up. It's not going to change anytime soon.
The quality of local broadcasters - both video and audio - is simply appalling sometimes. And it's allowed, almost encouraged, by the DMA system, for locals. For example, what motivation does a small ABC station have to upgrade to true 5.1 or even full-HD when most of its viewers are on satellite or cable and only get your station - and are only ALLOWED to get your station? Most of the DMAs around here have significant overlap with neighboring ones. If ALL locals were on satellite/cable in all the areas they are receiveable OTA - IN HD - then I think many of them would be forced to upgrade or lose many viewers.
As far as cables are concerned, I am pretty sure there is no difference between digital coax and coax. Why would you not use HDMI whever possible? As others have said, including the article, it's the best. I have optical from my TV to my Denon, only because that's the only option, but there are some that have the HDarc "two-way" HDMI audio.
