Damn, I thought I was running 5.5 but that's the current version. When I installed it on my Win XP Media Center box it won't detect the drives. I'm thinking it might be some Microsoft "bug" that forces you to use there proprietary CD Burning software but I'm not sure.
Nero 6 comes out next week so maybe I'll hold off until then But I'll double check the version I'm running tonight and post up. Plus I'll scour Nero's website and see if there is some kind of driver or patch I can update.
