I have a Yamaha RX-V461 Receiver and Def Tech Pro 1000 speakers - center, left, right and sub, but no rear surrounds.
Sound is fine with HD Cablebox using digital coax from cable box to receiver and using the "Straight" setting on the receiver.
But, when watching movies on DVD (Sony Blue Ray BDP-S300), the dialog is often muffled and hard to hear clearly. The DVD player is connected to the receiver with an optical digital cable. I usually set the sound field it to Movie Dramatic, and the Receiver automatically switches to "Virtual Cinema DSP" since I don't have rear surrounds. I have tried changing the mode to Straight, but that does not seem to help much.
To the extent the DVD menu allows for other audio options, I usually select Dolby Digital and assume that the receiver will decode it in a manner which will work best for my 3.1 setup. Is that a mistake? Should I choose some other audio option?
I used the auto setup for the speakers and they seem balanced.
So - any suggestions on how to improve the clarity of the dialog through my center channel and what are generally the best settings for a 3.1 speaker setup with these components?
Thanks in advance for any advice.
