Hi! Does your Receiver and TV have an ARC HDMI? If so:
PVR-> TV-> Receiver
otherwise:
If you want to hear audio only with the receiver on:
-PVR -> Receiver-> TV
If you want to turn the receiver on separately, and then have to turn down the volume on the TV so only your surround speakers are playing:
-PVR-> TV-> TV's optical or HDMI out -> Receiver
A DVD player will simply go to the Receiver, and then you just change inputs.
What speakers do you have?
