In reply to:
a. Optical out of the DVD player to the DVD optical slot on my Yamaha receiver (this is the cable lit red but you know that). What does this cable do ??
b. audio out cables from DVD player to DVD audio connections on receiver.
Umm... if I read that correctly... you've hooked up both the optical and analog audio cables?!? It's a "one or the other" situation... don't hook up both sets of audio connectors.
edit: the optical cable carries all your audio channels digitally to the receiver
