Holmburgers- the quibble should be over the term "hold back the burnt out lights". If the highlights in the negative are blocked up, meaning there is so much density in the negative that they print paper white, then you want to burn in the highlights when printing, not hold back. If they're REALLY blocked up, and not just by a stop or two, then pre-flashing the paper would be a good idea to put a little base exposure into the highlights so that they print easier. There are some really good threads here on APUG for how to do this, just search around.
