My receiver is connected to my network and recognizes mp3 and playlists created in wmp11. I wanted to try flac files so I ripped a few and created a playlist with media monkey but my receiver can't see them. I copied the flacs to a flash drive and put it in the USB port on my receiver and it works. So what is going on? How can I get my receiver to recognize flacs and flac playlists on my computer.
