The CD32 has a pretty weak laser. It was my introduction to the Amiga and I have experimented with them a lot. I have found that the "quality" of a CD doesn't seem to matter so much. It's the reflective surface of the CD that matters. Some of these high quality CD-Rs use a deep blue ink, which the CD32's weak laser just gets lost in. For best results, try to find some CD-Rs that have a shiny silver finish to them, preferably with a white "printable" label side surface, they're the most reflective and work best with the old CD32 laser. Also, make sure you burn them at the slowest speed, it seems to help too!
