How do I check if I have this?
In Nero, go to Recorder > Choose Recorder. Select your burner and look for "buffer underrun protection" in the bottom left corner.
In Alcohol, go to View > CD/DVD Manager. Select your burner and look for the item "Burn-Free Technology".
btw, unless your burner is more than 4-5 years old, you *should* have the burn-proof feature. so that's probably not the problem, but it wouldn't hurt to check.
Oh, and Eagle, it's buffer underrun, not overrun

. Buffer overrun is how you exploit windows' security flaws; underrun is what happens when you use up all your buffer and your laser continues to burn the CD with no data.
