I have a Pioneer reciever which as the following audio connnect options... 1 Digital Coaxial 1 Digital Optical 5.1 Analog (Where each speaker in a 5.1 system has it's own RCA interconnector from DVD to Reciever) Currently the Optical is hooked up to my HDTV cable box which is great. But I am confused what to hook my DVD player to. According to the manual the 5.1 Analog is best for SACD and DVD-A lisening, but for watching DVD's in general what is best? The problem is that I am limited in the audio options (setting that change bass and treble) when lisening through the 5.1 analog setup. When using the Digital Coaxial I have alot more options. What is the best setup?
