What is FireStarter FX?
FireStarter is a pure Cocoa, Mac OS X only burning application which will allow you to duplicate all kind of CDs (even those that other Mac OS X applications won't), burn VCDs and SVCDs, and have access to unique features such as overburning and CDDB access.
It's also a very easy way of burning disc images from the PC world:
It handles perfectly well cue/bin files, which are so common on Windows, and which were very hard to burn with other tools.
Plus, it's a very easy way to erase an RW media, without the hassle of Disk Utility.
What FireStarter FX is not:
FireStarter FX is not a tool to back up DVD-Videos, nor a transcoding tool to encode your videos in other formats such as MPEG4, MPEG2, MPEG1 or DivX (yet? ;-))

I've used it for a while and liked it a lot.
