Oh, forgot to say...

You have to do ;@DC for emphatic, too, or you'll get your player into a weird state where it can never synch. Or you have to remember to shut down emphatic before every synch. See the notes here.

In the case of Emphatic, it's trying to read the song info from the actual song files on the /drive0 partition, so synchs stop working because it can never mount/unmount drive0 while emphatic is running. This includes synchs to update the config.ini file.
