Tag "Grouping" in m4a not read by Minimserver

[bkraakman]

Hi, I started using the tag Grouping on my mp3's and m4a's and added them via itunes.
I checked if they where there on MusicBrainz Picard.
The tag works for my mp3's, but not for my m4a-files (both apple-lossless and aac format). The m4a-files are found in Grouping under 'unknown'.
I hope you can fix this.

Furthermore, I am very satisfied with Minimserver. I have it installed on my Synology Nas and play the music on my Yamaha musiccast system. It is fast (much faster then itunes) and I don't need the extra computer (running itunes) anymore.

The only things i miss is being able to create smart play lists (like genre contains 'jazz' to include jazz, jazz rock, jazz fusion, etc). Hence the use of the tag 'Grouping'

I also miss the possibility to search for an artist or album in the musiccast app, so tips on that are welcome!

Thanks in advance.
