I have two JB3's, I use one to record and use the other as an mp3 player. I'm having a weird experience, hopefully someone can help out. What happens is this--I will put a playlist into 'selected music'. Tracks play fine, but then when I power down the unit, then power it up a few hours later, the playlists are missing from 'selected music'! All of the other albums I had put in there are still there, but no playlists! Anybody know what's up?
