I have a Yamaha RX-V2400 that doesn't have hdmi capability, a Denon 2910 DVD with hdmi and a Panasonic plasma with hdmi and a digital audio out jack. I currently run hdmi from the DVD to TV and TOSlink from TV to receiver for the audio but my receiver never seems to recognize that there is a Dolby 5.1 or DTS signal. Is the digital signal from the TV just a "pass through" or would I be better off taking the digital audio directly from the DVD to the receiver?
