UPDATE: I have now seen the disc, and framegrabs have been posted here - chosen deliberately to match the DVD Beaver grabs of the Clavis disc. The Second Run version opens with the same logos as their Szindbád disc, confirming that this is the 2011 Hungarian National Film Archive restoration. The subtitles are white, and far better written - the Clavis subtitles (or at least the English ones) were sometimes baffling, and were even cut off at the sides on occasion (I have no idea why: I've never seen that happen before or since).
I have to confess to being sceptical about the 1.85:1 aspect ratio when I heard about it, as it always looked fine to me in 1.37:1 (as featured both on the Clavis disc and the 16mm projected screening that I saw about 25 years ago) - although I obviously bowed down to Jancsó and János Kende's authority. But now that I've actually seen it in motion, I can appreciate the difference. Hopefully these comparative grabs make it clear which is the correct ratio - and of course the Second Run disc's anamorphic enhancement helps too, as there's a fair bit more visible detail.


Incidentally, the Second Run disc includes the same episode of Message of Stones as the one on the Clavis - Hegyalja.
