Ok ok ok ok... My hifi seems to work. It spins up if I tap the lid slightly, and that's good enough for me. Other CDs work, it's just a set of 3 CD-Rs that don't appear to work. They work in my flatmates hifi, in so far as they play without distortion, but they give a disc error about halfway through the disc. I'm burning a CD of MP3s to test just now, and if that works, I'll assume it works fine.
