Hi all,

I have a SONY 725D dvd player.
Last week I brought a new integrated amplifier - PIONEER VSX-D2011

When I play a DTS ES audio disc the Surround BACK is activated on the amp
and I get a 6.1 "lights"

When I play a DD EX audio I only get a 5.1. The surround BACK does NOT
work.

Does the player is not "transparent" to the EX flag?
Why the DTS ES works on the same player and discs?

This situation was verified with films and the AVIA dvd test disc.

Thanks for all the inputs
