Any portable dvd player that reads m3u?

I want to buy a portable dvd player that will allow mp3 files to be played according to an m3u playlist. I also want the dvd player to be able to play dvd-+rw discs. I want to edit the disc to add new m3u playlists (accessing the mp3s that are already on the dvd). I also want to be able add new mp3s to the dvd.

Any suggestions?
