I expect it will be a long time before we see the OOT in HD, if indeed ever (the closest we'll get will be a fan recreation such as PaulisDead2221's Vintage Edit). And anyone who's examined the GOUT in detail, or tried to improve it, will know that some of the flaws of that DVD are irrepairable.
That is why we need a preservation that combines the best available laserdisc sources. Maybe I'll start Moth3r V2.0 this year.
