There is currently 3 versions of Robocop available to my knowledge. 1. Orion Pictures (I currently own) 2. Criterion Collection 3. MGM I am looking for the release that offers the best picture and sound. I rented the Criterion version a while ago, and If I remember correctly, it only a had Dolby Surround track. I think MGM has a Dolby Digital track. Orion is in stereo with an average picture. I know the Criterion version is rare and hard to find, which means I'll be spending more then usual to buy it. Which version should I buy/stay with?
