Hi, BrenR:

The coaxial inputs layout of my RX-V2600 are similiar to the RX-Z9 2,3 and 4 except 1. And it has same default settings. I reassigned the DVR to DTV. So i use the 3 and 4 for my two DVD players respectively. I suspect there is something wrong with my TV coaxial output, but it is hard to believe. I just bought it two months ago.
