"Verify Failed" in DiscJuggler

I have seen a lot of people posting about problems buffer underruns and not being able to record short audio tracks etc. But I have had no problems with any of that. Ocassionally though when I burn a game and set DJ to "Write & Verify" I get a failed verify in the same spot no matter how many times I try it with different media. The games seem to work fine still, but I am wondering if the copy is bad and maybe the game will fail somewhere in the middle or something. Does anyone know anything about this? Or if it is not a big deal at all. Thanks, cool forums.
