I never had any problems using recorable CD drives on any of my Amiga's. I'm using MakeCD for burning CD's without any problems. Here's a tip for y'all:
Don't mount CD0 at the startup-sequence, but only when you need to read/write data from/to a CD (when Workbench is already there). This way it decreases boot-time.
But wouldn't that go against the "plug'n'play" philosophy of the Amiga? :rtfm:
