Laserdisc has a few different formats: all analogue, analogue video with mono analogue audio and digital audio, or analogue video with all digital audio.

They key to a good capture these days is to get the best composite video converter you can find as the video is stored like a vinyl record, as an analogue composite video stream. So yes using the svideo on some of the newer players, the conversion of composite to svideo is still not the best. I need to find a link to a decent converter to 720p I have been using with vhs and am happy with.

Does anyone know if it is possible to transfer laserdisks to a modern
digital format? There are 16 laserdisks recently donated that have C
programming training from 1984, which was part of a UNIX and C
training program. The reason for the transfer is that we don't know how
rare these disks are nor how long laserdisk will last.

There are 16 laserdisks as well as supplemental floppy disks and some paper
manuals.
