Heres a manual for a Denon AVR-687 ,
I'm going to assume this is correct instead of DVR.
In the manual there is an image (not a detailed as I would like but maybe suitable).
Look at the Connecting a TV/DBS tuner actual page 14 but Adobe shows as page17.
I wouldn't worry about an optical connection right now. You TV may not have an optical output anyway. If it does try it after you get the 2 channel working.
I'm going to use the actual page numbers .
Page 4 shows a headphone jack on the front of the reciever,
I suggest starting with that & headphones.
If the analog audio "A" from the TV to the Audio in (looks like the 4th pair down)
has sound to a set of headphones . you know that connecting the speakers should also get you some sound.
Once you are sure your getting sound to the heaphone.
Connect the optical output from the Sony BDP-5200 Blu-Ray PlayerBlu-Ray Player to the optical in on the Denon AVR-687.
Page 8 shows which speaker outputs go to the correct speaker.
Wired per that diagram should work.
There was also some information on "Auto Set Up.
You might need to run that once you get it wired .
Looks like the Sony BDP-5200 Blu-Ray Player would use HDMI out to the TV . You shouldn't need to run analog audio from the TV at this point.
