thanks for the quick reply – mine somehow got erased, so here it is again:

We use precisely calibrated analog audio meters here, which receive their signal directly from the computer’s audio interface. It’s a great way of checking levels, particularly as TV mixing has such specific specs.

As an experiment, I ripped my own dvd and extracted the audio with quicktime pro – lo and behold, it peaks exactly where it should. That means to me that Apple’s DVD player recognizes and somehow boosts ac3 audio to 0db. Again, DVD player did not boost the level of a DVD burned with aiff audio.
