first of all I apologize for possible mistakes..
anyway I try to explaine...
well, in the rhapsody mach 4 you have
8 hdmi you can connect BD, HDTV, media player, ps3 etc..to.
Which source do you connect to balance outputs?
If connecting a BD to the balance outputs
does the sound during movies get better than hdmi?
and you can enjoy the same processing modes available
with a sorce connected via hdmi?(for example in the D2v you have digital DSP and analog DSP)
