If it's anything like I'm experiencing, it happens at random times with different media, but only on DVD's. My system is not corrupt and has been stable for a few years now with no significant changes (other than Apple updates). It only happens when using Toast (7 and now 8). Today it happened as I was burning my first DL dvd with the machine. In the past it has happened while making multiple copies of a self-made DVD. It would make the first two or three fine, but then get that warning on the remainder. I do not burn at maximum speed, usually about half (8x) with buffer-underrun protection on. I suspected the drive was on its way out, but it works too often for that to be the case.
