HELP WITH MY OPPO

I thought I could pass the video through the Marantz so I can still use it for switching sources and how TV is displayed. Didn't think the Marantz would degrade the signal? I had wanted to use them oppo video not just for movies but to upgrade the pic quality of my Sat. picture.  the oppo should recognize the HDMI on the Marantz to pass the signal but it is not" hand shaking" with the signal. Audio is done thru the 7.1 so oppo DACs are used. If I run the video directly to the TV I defeat the purpose of the Marantz's abilities. Does that make sense? 

I also have a projector so The Marantz passes the signal to mytv or projector. how doI get a signal to both sources with the OPPO? unless I use an HDMI  splitter to go from the OPPo to the splitter and then to the TV and projector. Really didn't want to do that. 

thank you guys for taking the time to help. It is much appreciated. I believe I got things working as they should. It was an HDMI hand shake issue in addition to setting the correct audio choices and inputs on the Oppo and the Marantz. Then I managed to get  my Harmony 950 set up for Macros. I tell ya I probably spent 8 hours getting this set up. 
Have the Oppo  Main out to the Marantz DVD input. The Monitor outs of the Marantz are going to the TV and Projector( which is the way it has been before the oppo was introduced). the a7.1 analog outputs from the Oppo to the Marantz 7.1 inputs and the stereo outputs of the Oppo to an analog (CD ) input on the Marantz. Seems redundant to have the 7.1 and 2 channel analog inputs for the Marantz. The 7.1 down mixes to 2 channel when a stereo CD or SACD is played. Or I'm I not correctly using the stereo outputs on the Oppo? My last question I swear!
