I haven't been happy with any of the linux burning options. I've used Nero for years. One of the first legit pieces of software I owned on a Windows Box. I'm glad they brought it to linux... However, since I've upgraded to an AMD64 distro... I haven't been able to use it.

I would use K3B, but frankly am not too fond of KDE and it's applications, with the exception of KDEwebdev (best web-coding software I've ever used). So I've been mucking around with Eclipt Roaster, GnomeBaker CD/DVD Creater, and Graveman. The all work decently, but I still prefer Nero. It's familiar and easy to use.
