"Cable from TV to DVD" - in what "direction" this cable will be used?

From the sounds of your Post the DVD player is the surround sound receiver.

If DVD/Receiver has multiple HDMI inputs:
Connect all devices to DVD/Receiver and then DVD/Receivers HDMI OUT to TV

If only one HDMI port (output) on DVD/Receiver:
Connect all source devices to TV via HDMI.
Connect TV to DVD/Receiver with optical. This will allow all other audio sources to go back to the surround receiver.
