DD EX superior to DTS ES Matrix?

[RichardMA]

I'm wondering about this because the DTS ES Matrixed
is not "flagged" on the DVD. Does this mean the accuracy
of the rear-centre decoding with a flagged DD EX disc
is higher than with DTS ES or other decoding method
for the rear-centre? I am not including DTS ES Discrete
in this question of course.

It's usually the other way around. The DTS-ES matrix track is usually flagged, and more times than not the Dolby Digital EX track is not.

I've found both to be about equal in separating out surround sound effects (although the DTS tends to have more ambiance and soundfield presense), but DTS-ES Discrete 6.1 beats them both.

Not true,though in many cases it's absent,[in my experienxe only JP3 is flaged in DD and most DTS ES titles are flaged]but it is only for the processor anyhow so it can turn on the EX/ES processing,which can be done manualy,and it doesn't have any issue with quality at all.As

Interesting. I read that DTS ES is non-flagged from
the manual of the Rotel RSP-1066 (pg. 15). I guess it
"could" mean that the Rotel does not recognize DTS ES matrixed flags on DVDs and uses some generic method to
extract the 6th channel from the surrounds?

is a matrix just a matrix?

or is there any significant difference between the 'official' decoders and using a generic decoder (or perhaps a pro-logic receiver)?

My explanation of how the Rotel 1066 handles flagged and non-flagged DD-EX and dts EX/ES material can be found in this thread...
