The files are on a hard disc attached to the raspberry. It is formatted with ExtFAT.
There are three situations I can try:
1. I access the library in the raspberry as shared library. Then the command »write tags to file« fails with an error message.
2. I access the files in a library in my mac which uses this network share. Then I get the message that the tags are written, which is not true.
3. I use Media Center directly on the raspberry. Here I get the same message and the same result.
In no case I can write the tags to the files. The only difference is: in cases 2 and 3 get the message that all is well.
But I ound another strange issue which may explain what happens. The Wiki tells about the »General settings« that there are three options:
1. Automatically Import Files into Media Center: Whenever you play a file associated with the program, that file will be imported (it will be added to the "Recently Imported" Playlist and filed into the various folders, including Artist, Album, etc).
2. Store tags in external sidecar files if the file type does not support tagging
3. Update Tags When File Info Changes: If this option is checked (default), tags will be updated when changes are made in the library.
There is only option 1 in the windows, when I open it. There is nothing about a »sidecar« and no option which would say that something is updated, when file info changes. This is the same on the Mac and on the raspberry. (There is a second checkbos, but the text doesn’t look like th german translation of point 3. point 2 is definitely not there. May be the option disappeared somehow?
