Setup is a Mac Mini/Synology 1812+ and Yamaha Aventage 3040. iTunes Library has zero duplicate MP4 files but MC22 has many of the same songs. As expected, I am seeing the FLAC files, which is ok.
Where is MC22 getting a second or third copy of MP4 files? No other library loaded. DLNA is off.
Looks like a great option if I can get it working. Thank you - Chris
