Are you using the same brand of media that you usually use? I’ve found that when I have a problem like the one you describe it’s usually an issue with the media that I’m burning to. Memorex, Maxel and Verbatium have worked well for me. Fuji disks have been rather hit-or-miss. They work fine in my players, but I’ve had a few clients who have had problems with them in their players.
At least that’s been my experience. Your mileage may vary.
