I don't believe there is such a list- that would require studios to advertise what they've done to the audio put on the DVD. Unless it's a new restoration/remix, they usually don't tip their hand to the consumer. If your playback sounds too bright, you might want to engage Re-Eq.
One would think that THX would want to get the information on which disks out there benefit by their Re-EQ as a selling point for their "certification." I've been playing it by ear since 2000, so I guess I can continue doing so. Thanks for the reply David.
