I have a Zen Vision M 30 GB.
I use the zencast organizer to send sync audio and video to my player.
You can use Zencast to subscribe to Zencast xml files as well as ipod xml file. I think it just find the audio/video links within the xml file and allows you to download them.
What I hate about the way it works is that the audio files you sync using the zencast organizer are filed in the video section.
Which means you will not be able to make it part of a playlist of things to play.
Audio files get filed as video and displayed as video. Which means your screen will not turn off when you lock they keys - a waste of battery.
That's my gripe with the zencast organizer.
