Using Fuppes 578 windows xp sp2.
CD's ripped to flac and tagged with freedb info.
Building new database, all files show up in directory structure.
Building new virtual containers results in missing songs in flac albums.
Never missing songs in mp3 or ogg albums.
Problem with tags in flac?
I used easy cd-da for ripping and tagging,
also tag&rename for tagging, no difference.
