Agreed. And reconverting the digital conversion to analogue, sending it straight into the laser pickup of a player, and having the player both act on the VBI data and display the image it was sent would be an excellent demonstration of the success of the process without needing to build a disc-pressing plant

This was actually something I was hoping would come out of MAME's laserdisc preservation efforts. More:

Also agreed. My thinking was that by focussing on arcade games at the start the basics could be established then built on from there. Most arcade laserdiscs were not overly-complex by laserdisc standards (video plus two analogue audio tracks, for the most part), which is common to the fundamental retail laserdisc.

Understood - that was partly a rhetorical question on my behalf, but it should definitely be the end goal.
