Check the dates. You'll find that the THX standard was established in 1990,
not 1993. The first THX Laserdisc did not show up until after (a) the THX
standard was established and (b) someone had built the necessary pieces and
put them in a studio.

TV was round in the 1860s. That doesn't mean that the standard used then has
any relevance to current production.

Which is not the same as high definition.

And when did the laserdisc standard call for high definition masters? Not
your wide SD 853x480 but HD?

That's _film_ transfers. If they come _from_ digital then they must be
going to _to_ film. This has zip all to do with DVD production or any
other kind of digital distribution.
