I recently tried converting my GOUT discs to 16:9, which I have done for a number of my LD rips or letterboxed DVDs without issue.
It turns out that the GOUT actually has a shaking/shimmering problem with the image that is headache inducing.
If I zoom in on the GOUT disc on my TV I don’t notice it, but when I have the raw video file converted to 16:9 and use a media player, it’s unwatchable.
