Surround sound will only be produced if the the broadcast TV program has suitably encoded audio. Also, even if the tuner is receiving surround sound, the TV must be equipped with digital audio out (optical or co-axial) to send to the Denon. Ensure that you don't just have stereo sound ( 2 X RCA red and white) coming from your TV.

The best possible solution to your problem is :
Connect your blu ray player directly to the HDMI input of you Plasma and watch HD video....
and connect the 5.1/7.1 sound thru the optical or the coaxial link directly to your AVR 3805.
You will not loose anything on the Blu-Ray.
The sound is best processsed by the AVR3805, while the video, which is the real upgrade (BluRay) in terms of resolution of picture would be processed by your plasma.

Connect and Enjoy

Could be a number of things.
Most likely your surround sound mode. Some people dont like Dolby. Try to switch to 5 channel stereo.
Other option is to turn the center channel speaker channel volume up. Voices and dialog come from the center channel speaker in Dolby modes. Post back if you need instructions.
