I have a BDP-103 connected to a Yamaha RX-A2010, which has HQV Vida video processor. Does anyone has any recommendations on whether I should do both video+audio through the Yamaha or connect video directly to the TV? Any recommended settings on either the OPPO or Yamaha?
Normally 1) there is no benefit in connecting the Oppo separately to both the TV and the Yamaha (triangle connection); it complicates the handshaking, and it requires an extra cable
You should continue using a chain connection (Oppo -> Yamaha -> TV), and set the Yamaha for "video pass through"; then the Yamaha is only processing the audio and not "messing" with the video...
1) Strictly speaking, there is a case where you might need to use a triangle connection; namely if you watch 3D movies and if the Yamaha is too old to support HDMI v1.4 3D video pass through; I don't know your Yamaha's specifications so you need to check that yourself...
Like tokyoav, I also have a 103 and a Yamaha RX-A2010 -- which, although I don't care about 3D, is HDMI v1.4 3D compliant.
Even so, I still "split" the Oppo's HDMI output (HDMI1 directly to my non-3D 58" Samsung plasma, and HDMI2 to the A2010). I also have a DirecTV "Genie" (along with a Toshiba HD-XA2 HD-DVD player) connected to the A2010, via its other HDMI inputs... and the HDMI output from the A2010 goes into a second HDMI input on the plasma.
I do not, by the way, "stream" anything. I'm purely a "shiny-disc" guy... so I never watch films on TV. I do watch the morning news, a fair amount of sports, and a couple of TV shows, though... which leads me to my point.
There have been hundreds of posts in this thread about improving cable/satellite TV video quality by running the HDMI outputs from the TV boxes through the Oppo's inputs. Personally, I've always found these posts to be confusing, because to my eyes, the HD output from the "Genie" couldn't possibly be better... and I believe it's because the A2010 is doing just as good of a job of upscaling the Genie's output as the 103 would.
So in my "split" situation... allowing the A2010's video processing abilities to remain "on", I get the benefit of best-possible-quality "televised" video from the DirecTV box, without the Yamaha "messing" with the HDMI video output from the 103 at all, when I'm watching a Blu-ray.
