[ALUG] Recommendations for software to use with Creative Zen MP3 player

What do the panel recommend to use with a Creative Zen MP3 player. Main requirement is to be able to download MP3s and put them onto the Zen, it's not a requirement to be able to play them on the computer. Podcast synchronisation would be a plus but lets try walking before we run. Doing this on windows has turned into a disatrous mess. -- Chris Green
