That being said, very few TV programs make any real use of Dolby
Surround. When I play a DVD I'm surprised if it doesn't have at
least 4
channel audio, but I'm even more surprised when a TV show on cable has
anything on the rear channel. Usually almost everything is through the
center channel.

One of the first shows to use surround sound encoding was the old
"Arsenio Hall" show. This caused a lot of problems because most
stations transmitting stereo use a "monoguard" to detect and correct
an out-of-phase condition, which will result in almost inaudible
sound on a mono receiver. Since the encoding used phase modulation it
drove the monoguard crazy, switching back and forth trying to correct
what it detected as a "fault". Stations were given no warning of this
at all and it was a real problem. Eventually everyone just switched
off their monoguards for the program but it still created strange
sounding stuff on a mono set.
Just thought you might be interested in some ancient history.

A similar thing happened when Star Trek: The Next Generation started
their first season. It was in Dolby Surround and made decent use of
the full field. Apparently in NY everything was fine, but when I went
to my parents' house in Florida it sounded like garbage.<br>
