I sometimes use the 7ch all stereo mode when listening to FM radio or CDs but mostly 2 ch stereo as the bass sounds better through my 2 subs.
For TV and movies I use the PrL11X-M music mode rather than PL11X- C cinema or Neo 6
Apparently the cinema mode doesn't channel as much volume to the surround rears in cinema as compared to Music.
Correct me if I'm wrong? - Cheers
