The sunset does look interesting. You're probably right in saying that they just forgot to put post production coloring on it, which could have been the case in those days.

Looking at your sample, it looks honestly really good, msycamore. Sure it's a tad it soft since it's from laserdisc but that doesn't really show that much. As far as crosstalk, in the clip, I didn't see much, so I, for one, probably wouldn't be bothered by it. Colors do look nice, and it has no clipped whites. Furthermore, the optical grain was nice to see. It looks more natural, as opposed to the more scrubbed look of the GOUT.

Certainly, the quality of this is similar to Arnie d.'s V8 (though that was from the JSC). Speaking of Arnie d., if you really can't live with the crosstalk of this release, he was offering raw X9 captures of the (similarly, smear-free) JSC trilogy to anyone willing to finish it up.

In conclusion, yes, I'd be very interested in you doing this after finishing up on THX.

EDIT: Do you mind kindly uploading a sample of the sunset scene? It looks good, no crosstalk, judging from your sample picture.
