This hint leverages built-in functionality and should work from a base install. Disk Copy's functionality has been folded into Disk Utility in Panther. I classify this hint as a 10.3 hint because I have never tried it in earlier versions of Mac OS X..
In order to create a cross-platform disc you need to:
- create and name a folder set to the desired name of the disc. (ex. MyDisc)
- Fill that folder with the desired contents of the disc
- Open Terminal, go to the folder's parent directory and type hdiutil makehybrid -o MyDisc MyDisc/. This will create a file called "MyDisc.iso"
- Open Disk Utility and click Burn. Select MyDisc.iso as the source, and start the burn.
This should give you a disc which can be read by nearly any Mac, Windows, or Linux computer.
