If your receiver has optical outputs, you could connect the Blu-Ray player directly to the television, and then send the audio out via Optical audio (at Bitstream settings in the Blu-Ray player).
I did a quick search for the manual for your unit, and here's what I found:
#2 (4th from the top) is the BD input:
And you should be able to feed the optical audio from the Blu-Ray player into that input on your receiver, and run the HDMI straight to the TV for the video.
It may also work at 1.3 standards without the audio cable.
Also, once it's connected, don't forget to choose the Audio option on the Blu-Ray/DVD that denotes 5.1 or 7.1 surround as your audio output, so the right audio track goes to the receiver.
Give it a try and keep me posted.
I'm considering upgrading to a UN55C8000 3D LEDTV and a BD-C6900 3D blu-ray from Samsung. I bought my home theater equipment back in 10/2008 including a Pioneer VSX-94TXH A/V reciever. I was told the BD-C69000 runs a 1.4 HDMI where my reciever runs a 1.3 HDMI. I guy at Best Buy told me that since the BD-C6900 only has 1 HDMI input, I would have to get a new receiver than runs 1.4 in order to get dolby stereo sound. Instead of doing that he told me to check out Panasonic's 3D Blu-ray player since that has 2 HDMI inputs. I also hear I may be able to use a upgraded HDMI cable to make this work.
On top of that, CNET just reviewed the BD-C6900 and commented:
"The BD-C6900's connectivity is a step above most competing players thanks to its inclusion of 7.1 analog outputs. That's a nice plus for people using older, non-HDMI AV receivers, as you'll still be able to take advantage of both Dolby TrueHD and DTS-HD Master Audio at their full resolutions. It's also a plus for anyone with existing HDMI-capable AV receivers that lack HDMI 1.4 compatibility. This way you can send 3D video straight to your HDTV and use the analog outputs to connect to your AV receiver."
- which leads me to believe I could make the BD-C6900 work with my existing reciever. Before I buy can anyone steer me in the right direction? Much appreciated!!
