I thought while we’re all trying to preserve various bits and pieces from laserdiscs lately, that I would ask if anyone has successfully ripped PCM audio from any of the Superman laserdiscs?

I understand the blu-rays have the original 1978 audio in DTS-HD, but I would like to try and preserve the original 1978 sound from the laserdisc and to also see if there are any real differences. And it would be nice to sync the ld audio with the blu-rays as other optional tracks.

Furthermore, alternatively, we could try and preserve the whole laserdisc with the video as well, as I know some people have always wanted to see the colour timing before it changed on DVD and Blu-ray (myself included) but I assume this is a bigger undertaking.

Not sure how many are fans, but thought I would ask anyway!
