Does anyone know if the Denon 1909 is able to map 5.1 Dolby True HD / DTS-HD Master Audio into 7.1 mode? I have read in the manual for the Yamaha DSP-AX763 that all processing is disabled for these sound formats but the Denon 1909 manual does not say that it can't.
I am just not clear yet as to if the Denon can indeed generate signals for the rear surround speakers from a 5.1 HD source.
Any thoughts???
