I'm still working my way through the mysteries of the Zone 4 output, so I'm turning again to the experts here for an answer to this puzzle.
I thought if I set the Zone 4 output passthrough to DVR, it would always feed the DVR signal. And yet when I change the main zone to some other source, Zone 4 changes along with it. And I have to manually set it back to DVR. This seems to happen every time I change the main zone to a different source.
Am I doing something wrong or is this a 'feature' of the 4520? Thanks in advance for any assistance you can render.
