Why not connect the Blu-Ray, Dish DVR to the HT system via HDMI, and then the Nintendo with either component (better) or composite (SD), and then output the picture to the television with HDMI?
Have you changed the audio inputs to send bitstream to the HT system? It's likely that it would be able to decode some of the signals - and for those signals that might have trouble, you could use PCM as the setting.
Just a thought.
I just bought a Samsung HW-C560S Home Theater System and I would like to connect everything the best way possible. I have connected the sound part of the system with little trouble and I tested the speakers with the built in tester. All sounds good but the video connects do not work well. I created a diagram of all the inputs and outputs of all my equipment. (See JPG link. http://public.me.com/deg/Home-Theater-Settup.jpg )
Here is the text list.
Samsung HW-C560S Home Theater System
Samsung Blu-ray BD-C6500
Dish Network HD Solo DVR VIP612
Samsungs TV LN40B650 40" 1080p LCD TV (2009 MODEL)
I have a bunch of HDMI cables, and 3 optical audio cables and a component connection cable for the Wii (bought separately). I would like to use the Samsung AnyNet + feature if this is possible just so I can minimize the amount of remotes. I am fairly technically minded and I have tried a few configurations but none seem to make everything function the way it should. I have tried the Samsung website and I downloaded all the manuals for everything.
Please help. I know you guys are the experts.
