Digital recognition. After assigning the digital inputs as [1]DVD [2]DBS [3]CD,the coaxial cable for DVD recognizes the digital signal and allows switching between digital and analog modes. The same is true with CD mode, but with an optical cable. When trying to use the DBS optical digital input, it only seems to see the analog signal, for it will not switch to the digital input. I have verified the signal is present by using the optical input assigned to CD. I also changed the assignments to prove it isn't the specific optical input. It seems all digital inputs will accept the signal and function properly. Unfortunately, the receiver will not switch to DBS(digital) from TV(analog). Can anyone help?

ok a bit confused, Tuner ? like amplifier or Tv Tuner ? regardless seems like a easy fix .

First your cable box as 3 cables:1st . Power cable to outlet
2nd. From the wall ( usually a Coaxial cable coming from outside box ) into cable box.3rd. HDMI or Second coaxial cable ( One of these usually goes to the back or side of your Tv depending where inputs are located.)
Now Dvd has 2 cables 1st to Power2nd. To TV ( Hdmi or Coaxial )
On the back of your Tv will have 2-3 HDMI inputs . Assign 1HDMI jack to each media your trying to use.In this case TV HDMI 1, HDMI 2 DVD.
Assigning HDMI's will now reflect on your TV menu selection. Choosing HDMi 1 or HDMI2 from Tv menu will allow you use or view desired Media option in this case DVD or TV.
Now if there is Amplifier / Tuner involved like to connect surround sound to, connection may be a bit trickier however same principal.Plug all media into HDMI 1, HDMI 2, respectively,this time to the back of the tuner NOT to back of TV.Once you have done that You will need a third HDMI cable now from the back of the Tuner ( output Jack, usually has lighter color markings indicating Output HDMI) to your HDMI 1 jack in the back of your TV. Now you have bridge TV/ Cable , DVD into Receiver / Tuner and Selecting media will now be done not through TV Menu as before but through Tuner / Receiver menu or selection.
Good luck .

Good Luck

You need to assign a digital input (optical 1 2 or coaxial 1 2..) to a source (DVD CD etc). You can do it in setup menu > input assigment. Some receivers have preassigned inputs, check labels you your receiver next to digital input. Ex If it says "Opt1/DVD", select DVD and receiver will play a signal from optical 1 input.

The Dolby digital signal is outputted only through the Optical or Coaxial socket of the CBL box. you will have to get an optic fiber or coaxial cable depending which cable box you have and connect it to the digital input of the Denon receiver. The Denon's digital input are already assigned at the back. Eg: Optic input might be labeled CD so if you are connecting the CBL box to the optic input remember to select CD on the Denon to hear the cable sound, same goes with the coaxial input.

Read you manual, there is a page with a matrix of the audio in selectiosn that can be made for coaxial and optical on each input. Then you have to go into setting button on the right side of the unit and the "push set" knob to change the inputs for the digital audio.
My problem is, I had this all working and went to change the inputs around to add a optical DVD changer and now niether of my optical inputs are working any more. Analog is still fine.

HDMI signal from DVD can not be down converted to analog component signal.
Connect your new DVD to a component input 1..4. Make sure that component input assigned to desired input (dvd/vcr/sat/) (setup - input setup - input - component assign - component x etc). Connect coax output of DVD to coax x input of the receiver and assign it (setup- input setup - "input" - digital assign ..). Probably you need to setup DVD output resolution to 720i or 720p in dvd setup menu.

Each digital input is assigned a name and a function by you. You have to dig out the manual and assign the digital inputs.

My $.02. Why do you not want to use the coaxial imputs? There is no functional superiority of one over the other BUT coaxial is a) cheap, since it uses standard RCA cables; b) adaptable, since you can splice or split them among two devices; c) not delicate or prone to failure due to tight bends. I share one coaxial input between two digital device with an RCA splitter cable. Just have to make sure to turn the one I'm not using OFF. Try that with optical.

There are four digital connectors on the back of the unit: 2 optical and 2 coaxial. They are marked a s 1 2 3 4. 1 and 2 are optical, 3 and 4 - coaxial. Also you have front optical connector marked as F.
You can connect 5 digital sources to your receiver. For example, connect your DVD to input 2 (optical) by optical cable and connect your DSS to input 3 by coaxial cable. Assign DVD to digital 2 and DSS to digital 3 in input setup menu.

Normally the optical inputs are disabled unless specifically turned on. I dono't know your specific model. I'll research the model and update this with more specifics.

I had the same problem with my PS3. I have a HD cable box with HDMI out, a Sony DVD player with HDMI out. The Sony receiver STR-DG800 only has the HDMI inputs (sat/tv and dvd) and the HDMI is only a pass through port and will not decode audio.
I purchase a HDMI 4 port switch from Newegg (HS-41A0 http://www.newegg.com/Product/Product.aspx?Item=N82E16812168003&Tpk=HS-41A0) to hook up the DVD and PS3 to the DVD HDMI and switch between the DVD player and the PS3. It took me several days to figure out how to make this work with the settings on the reciver.

1 the DVD player must use the coaxial in jack for sound on the receiver.
2. the PS3 must use the optical connection on video1
3. the sound settings in the PS3 must be set to PCM
4. set the sound setting on the receiver to the following

a. on the remote press AMP button then the MENU button, next press the down arrow to you see 5- AUDIO SET - then press enter.
b.set sound decode priorty to PCM
c. next scroll down to you see digital assign - press enter
assign VID1 OPTICAL to DVD ( this allows the pcm output from the PS3 to play through the receiver), next assign DVD to COAXIAL setting DVD to DVD (this allows the digital sound to play from your DVD player).

So when you use your remote and select DVD, you can use your PS3 or DVD through the 1 DVD HDMI port.

Yes and no. You can get some digital signals to go to zones 2 & 3 but only PCM ones, Analogue always goes. I have a Denon DVD player connected to my 4306 with a denonlink cable. I had to connect RCA Analogue cables to the DVD input to get the sound to come out on Zone 2.
