Na you have to pay for Disco. I would also recommend Toast but sadly there no demo's to try it out.Are you talking about just burning data disks? If that's the case, Finder has burning built in. Just put the disk into the drive and it shows up in Finder. Drag files to it and press burn in the bottom right corner. For music, there is iTunes which can burn audio cds, mp3 cds. If you want to burn .iso or .dmg's to a disk you can use Disk Utility in your utilities folder in your applications folder. I assume that if you create a dvd with idvd you can burn dvds with that. BUT, if you are still inkling for more functionality, there is always Toast Titanium 8 which burns lots of stuff. Alternately, there is an app called Disco that burns stuff and it looks like its smoking or whatever... I think its stupid but I think its free so meh.
