As for two other missing links between LD and DVD (if you can actually call the foloowing that), I remember two CD-based media, The Beatles's
A hard day's night made by Voyager, and Eric Idle's
The Rutles - All you need is cache made Sirius, I think. Both were made for Windows 3.x.
A hard day's night by Voyager consisted of about 10-15 QT clips at a resolution of about 60-100 lines, plus lots and lots of extra features, gimmicks, material, and info. The first 3-5 clips had 16bit sound while the rest had 8bit sound instead. I've watched that CD so often it's pretty worn by today, which is why it's a good thing the film wasn't on the CD as one single clip, so only one clip of them is unreadable now. Even though I own that films DVD today, that old CD still comes in quite handy for all those nifty gimicks and informations, such as the complete script in three versions, the way Alun Owen and The Beatles's themselves wrote it during one weekend, the way it remained after adapted for shooting, and what bits were impromptus while shooting. There was even a function to play all three versions on one, in-sync to the film itself, with all three versions signified by different fonts.
The Rutles, however, was a bit more sophisticated in technological terms. Based on so-called 'Motion Pixels(tm) video compression technology' ('doubles as an extra household VCR - ideal for kids') and burned on two 'MovieCD's instead of one CD, it came with an own codec (though in AVI containers) and player and in 640*480 resolution at max size (while smaller resolutions could be chosen).
PS: Oh no! I've just found out that Motion Pixels codec doesn't work beyond Windows98. Simply clicking on the setup file produces a crashing process. Some net research (to see if I could find another, newer codec setup) told me all those companies involved with that codec are gone today, and obviously no free download urls ever existed because they claimed to have a patent on that codec while actually they never had that patent.
PPS: Guess an older Windows simulation is the only solution now.
