Thanks for the response, Jim.
I understand the basics of how that works...I am using a different universal remote with codes borrowed from an old VCR remote. Works great for play, pause, next track, previous track, stop, etc.
Its just those 2 (next playlist, previous playlist) that don't work. Next playlist plays one of the playlists and always that one, no matter how many times I press the button. Previous Playlist plays a different playlist but always only that one.
