Re: HDMI Connect ???
No, you're Denon 3806 will only accept video and coaxial (DD DTS) from the HDMI connector. If you want to use the Oppo for SACD/DVD-A in multichannel you will need to connect the six analog RCA connections to the MC input of the Denon. You should use the HDMI for video and you can use it (or add another digital connection to the 3806) for DVD use (Dolby Digital and DTS) but you will need to use the analog outputs of the Oppo for multichannel audio.
In this setup you would then need to run an HDMI cable from your 3806 to the TV as well.
