If i read it right, there is only PL2X done on the signal. The decoding was done in the DVD player, and in the PCM that comes out the EX flag is not longer there. So if you want 4 sourrounds you have to run PL2X.
No native EX processing is done in the preamp any more when you use MHR.

Not that i mind, do not like THX processing anyway.
