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.
