I have an issue with Linked Playlists. When I create the playlist in MS Media Player, all files are there; link to Mezzmo, all files there; when I try to play on Samsung C6500, only a small number of the files appear. Sometimes it errors with database errors presenting themselves. Smart playlists play in their entirity. There appears to be an issue with Linked playlists. I hate to have to recreate these manually in Mezzmo. I would love to be able to do Smart playlists using multi-keys as well. This would elimnate need for Linked Playlists.
