I am in Moraga and have a 3412 DVR. I've noticed channels such as TNT showing programs where the guide shows DD 5.1, my receiver shows a 5.1 signal, but there is nothing on the L and R surrounds.
This is always true of TNT
Sometimes true of UHD and NBC and ABC and CBS. Fox seems OK.
I am not talking about DD but DD 5.1 Sometimes the guide shows 5.1 when you first hit the channel and then changes to DD. The receiver shows DD. I think thats OK.
I am talking about DD 5.1 on the guide, the info screen on the channel and the status screen on the receiver all showing DD 5.1 or 3/2.1, and the side surrounds having nothing.
To check this if INHD2 is a still logo screen with music in your feed, it has the 5.1 flag and the music is present in all five channels.
Comcast first tried the user error bit. Then rolled a truck, called the office twice and agreed that my equipment was set up correctly. The tech put in a new 3412- no change. He promised to take the problem up with more knowledgable staff and get back to me. Of course no one has called.
I asked my neighbor if he had problems. He said no and invited me in for a look. Sure enough it said 5.1 but nothing on the left or right on TNT or UHD. OK on 24 Hrs, but not on NBC. He called later to say the Law and Order seemed to be OK. I've posted in another thread and found one person with the same problem and the only common factor is Comcast and a digital box.
Is anyone else in the Bay Area having the problem-- a program you know to have a 5.1 sound track, a 5.1 logo on the guide screen, and your receiver picking up the DD 5.1 flag, but nothing actual on the front surrounds?
I excluded rear surrounds as they may have matrixed sounds derived from the front if you are using PL2x.
The fact that an opinion has been widely held is no evidence whatever that it is not utterly absurd.
