Verbatim single-layer discs have worked for me. I haven't used their double-layer. I bought Verbatim due to a recommendation from the old MacFixit Forums. I had been using another brand (I don't remember which but it was a major brand) and every one of them turned out to be coasters. I have long since discarded them.
