What setting do you use for best DVD playback?
I found posts for Blu Ray playback, but didn't see what are the consensus optimal settings for DVD playback.

also while we're at it - what settings for Blu Ray playback (other post only has 1 reply)?

FWIW - I have a 120" front projector

You'll have better luck with your questions in the Blu-Ray player's forum
