I’ve been planning to do a RoboCop Criterion Collection HD upscale for a while now, and I just want to know, should I use the Laserdisc version for both the audio and the video? Or should I use it just for the audio and use the DVD for the video?
Generally speaking, if a well-handled DVD transfer from the same source is available, it will look a great deal better than the equivalent laserdisc. Other opinions are available here, but IMO it’s especially true of the Criterion Robocop - a marvellous picture for a non-anamorphic transfer.
Soundwise, you do want the uncompressed PCM from the laserdisc. Terrific track.
something wrong with the bluray?
The Criterion Collection is the only version which has an aspect ratio of 1.66:1 (every other release is 1.85:1), plus certain scenes like Murphy’s death has a different sound mix.
