Okay, I've been banging my head against a table for a day trying to figure out how to create a playlist that includes all tracks on my player. I'm not sure of the version I had before, but previously I went to the root directly then went to playlist and "create playlist", which created a "root.m3u" file that was the playlist for everything on the player. After the upgrade to 3.1, the playlist section in the main menu (which claims to still exist in the documentation/wiki page) is missing. I go into "Playlist Catalog" and try to create playlist, but just get a prompt to name the playlist, if I go ahead an name it I just have an empty playlist. This should be one of the simplest things to do on the device so I'd be curious to know what's going on. I've had to restore to using a third party playlist creation tool (used with the player hooked to acomputer) to create the playlist file I want. It would be nice to know how to actually do this on the device.
