There are a lot of single frames intended for use as stills, some short
videoclips, and a *lot* of data.  There's a huge amount of Ordnance Survey
mapping data on the disks, for example.  The data is read using the SCSI
bus, and that's also used to control the player when displaying stills and
video.  IIRC three of the sides are CAV and one is CLV (or maybe I have
that back to front?) and three sides are data/stills with some clips, the
fourth is all video.  I still have my disks but sadly no Master AV nor the
laserdisc player.
