You do have a digital output on the DVR though, you could run it to you receiver.
Of course!...But that would be too easy
Here is the deal...
My receiver has 1 coax and 1 optical digital audio input. It will auto select whichever input has signal on it.
The TV is coming in optically and the cable box and DVD player are "Y'd" to the coax.
The source that is on will pass into the receiver if the other sources are off.
Has been working great for a long time now.
Soooo, if I hook the PVR to the receiver via the optical and set it to record, and then watch cable , it will still "command" the input and I don't get cable box audio.
I have discovered that if I hit the "pass through" on the PVR remote, the audio stream stops and releases the receiver input.
So, you can see whay it would be nice to have the PVR digital audio pass through the TV and I use the optical out of the TV for both OTA and PVR audio.
I did search the forum and it seems this HDMI pass through is not an unusual situation.
I don't want to spend yet MORE money to buy a new receiver but maybe I'll check the "for sale " section...
