The KHYBER RIFLES transfers in Australia+ Spain were different. The Oz version was in mono, the Spanish version is in stereo. There was a flaw in some of the Aussie pressings too, though my copy seemed OK. I have opted to get the Spanish dvd as I love the Bernard Herrmann score and also like the way Fox was recording dialogue in stereo in the early days of CinemaScope (ie. traveling sound when characters moved across the screen). When I receive it, I will leave a post if I think the image on the Spanish dvd is superior. Both- like the upcoming Fox MOD- are letterboxed, so I'd be surprised if the UK version is in 16:9.
I haven't seen the MOD of THAT LADY IN ERMINE, but my German copy (a double feature with CLUNY BROWN) looks very good, especially considering it's taken from Eastman color protection negatives (or Inter-positives, forgive my ignorance, all I know is the 3-strip Technicolor negatives are no more).
For those who may not know, FANNY (Caron), OLIVER! and GUESS WHO'S COMING TO DINNER have been released on Blu-Ray in Germany.
