HDADULT

I need an external dvd burner for archiving data and making video masters. There are so many damn choices. Does anyone have one they are very happy with? I use PC's for office work and Mac/Final Cut Pro for editing. I would like it to be able to work on both OS's and have firewire and USB. Also if it would be able to out HD-DVD and Blue-ray when available. I am asking alot but thanks in advance for help!
