If you've ever inserted a blank CD-R or DVD-R, you'll know that OS X has a built-in disc burning ability. It also comes bundled with the Disk Utility application for, among other things, burning disk images. Despite this, Roxio's Toast 6 is still generally considered as one of the "must buy" apps due to it's much more extensive support of various CD and VCD formats, not to mention dual-layer DVD support. Given these facts, I've always wondered what it was about DragonBurn that made it worth US$50. It appears that this is one of the reasons.
