I've found the easiest way to make hybrid CDs on MacOS X is to:

1. Create a CD sized disk image (using the Disk Utility)
2. Mount/Attach/Open (choose your favourite verb) your fresh DMG
3. Copy in your directory structure and all the files
4. Set it up precisely how you want it to look under MacOS with icons/backdrops/file placement etc.
5. Execute the following command in a terminal window:

   hdiutil makehybrid -o <iso_filename> <dmg_filename>

   Take the ISO image and burn away.

This will quite happily create an ISO image with:

• HFS (MacOS) extensions
• Joliet (Windows) extensions
• RockRidge (UNIX) extensions

Meaning that it should work fine on virtually any platform...

Incidentally, the 'hdiutil' command-line utility is great - allows you to do everything Disk Utility does and more. Anyone looking to do CD/ISO/DVD image related work (and who hasn't done so already) should definitely type 'man hdiutil' into a friendly terminal window :o)
