I want to start with FLAC files via Mediatomb. They work fine on my Philips streamium (although without album art).

However, on my Yamaha RX-V2067 they do not work. The directory which only holds flac files is grayed out in the display. I cannot see or select any of my flac files.

The machine can play the files, which was verified with an USB stick. However, via Mediatomb, I do not see these files.

Any suggestion is appreciated.
