Of course, R2-6 received this version of the film in PAL format and have been subjected to the usual PAL speedup issues.
Retiming 25fps to 23.976 during encoding is actually quite easy once you've figured some "secret" tricks -- here's an example involving the encoding tool AutoMKV 0.98.4:
(Assume you've ripped your PAL source media, merged the VOBs (or what-not) and now have a single large 25fps MPEG2 or VOB (etc) file prepped and ready for encoding.
* click the Advanced Profiles Editing tab, and look center-right
* for Change FPS, adjust the two associated boxes from "NONE" to, respectively, "Assume FPS" and "24000,1001".
-- That's it! (Set everything else up as you were going to anyway, and encode.)
If this needs to be an as-lossless-as-possible step in a sequence, select AVI/XVID with a Constant Quality profile and a Quantitizer of 1 -- this will result in a large, barely-compressed high-quality file.
(BTW, I can't speak highly enough of the adaptive degraining "LEM" filter included with AutoMKV)
