Hello Jim & Matt,
Really glad to see recent updates of the JRiver including enabling to change sample rates in DLNA server and be able to play multi channel music with multiple Mytek DACs. I am sure you've put much effort in updating, especially the MAC version. But I've found some issue about the multi channel SACD ISO files I ripped from PS3, mainly from the three channel SACD ISO files of RCA and four channel SACD ISO files of Pentatone. These multi channel ISO files were recognized as Five channel instead of three channel or four channel they are supposed to be. Would it be a fix about it?
