The Creative Zen mediaplayer is not directly supported on the Mac. I use the following software to transfer media to it:
- XNJB is a program to transfer files from and to the Zen.
- Visual Hub can convert video files to the AVI format that the Zen supports.
- Handbrake can convert DVDs to AVI.
Note: to access the SD memory card in the Zen you do not need any additional software. You must enable it as a removable drive on the Zen and then it will appear as an USB drive on the Mac when connected.
