Did you ever figure out why you were burning so many coasters? I've only had one bad DL burn in the last year, and it was because I was trying to use way too many resources while it was burning. I had After Effects open and CCE encoding a video. Also, I can't remember the site, but you should be able to look up your burner to see what media burns best with it.
