I noticed that the on the uhd discs for ANH & ROTJ they have hardcoded subs for the alien language parts, while the foreign language versions have these sections without hardcoded subs , via seemless branching. Going to be a pain in the ass for editors wanting to use them as a source. I don’t know if the blu-rays are the same though.
Not too much of a pain if people are informed that 800.mpls gives you hardcoded subs. At least the clean versions are on the discs.
The 4K prequel discs are the same way. Rise of Skywalker is not, and doesn’t seem to use the standard typeface for forced alien subs.
