A few months ago I got my Sony STR-ZA810ES receiver working with simeple contol 4. I see that there is now support for the STR-DN-1080 in SC5.
According to sony the ZA810ES and the DN-1080 use the same command set, but the za810es is not discovered by SC, nor when adding it manually can I tell it to use the DN-1080 command set. The only one that still works is the DN-1070 Zone 1 commands. Neither the STR-DN-10X0 Zone 1 or DN Models command sets work.
