i'm trying to find a website that you don't have to pay to join where they have good information on DVD production qualities picture, sound etc. anyone know of any?
This one, for starters. The latest reviews can be found in the top right column of the front page, and a link to archived reviews is there as well.
DVD-Basen is a great database of DVD reviews for all regions. If you're looking for the easiest way to find multiple reviews of a DVD, this is the place to go.
