Configuring the avr playfi device as a Generic NTSC with transcoding enabled did not work when paying a flac or mp3.

I changed the device back to Microsoft Windows Media Server and found that mp3s play and transcoding of flac works.

PlayFi clearly advertises their support of flac and documents features for hi-res streaming, this is surprising. Perhaps there is something in the way they are advertising their supported mime types and a new device profile is needed?

Likewise for browsing mezzmo from the playfi application was odd when other DMS's worked. I've never encountered this before.
