Next week, I will have in my possession the 330-minute version of Napoleon on three DVD-Rs and I have been told that the quality is very good.
I recently obtained (what I believe/assume are) the same set of three PAL DVD-Rs.
I suspect, however, that these discs contain the 1989 version that rollotomassi and HerrShreck discussed on the previous page.
Thames Television in association with the British Films Institute
A special video version of Abel Gance's 1927 masterpiece
Made from the most complete print restored by Kevin Brownlow with the technical assistance of the National Film Archive
Now, I'm in the States, so I don't have as great a sense of what's going on in Britain, but I'm quite certain that Thames Television no longer exists and that Brownlow and Davis no longer work in association with them. (Although some of Thames Silents productions have been released on DVDs like The Buster Keaton Chronicles.)
I don't actually have knowledge of what scenes have been altered in what way in the 2000 and 2004 restorations, so I don't know where to look for definitive comparisons. I understand, however, that Brownlow found many original takes and edits that were only available as second choices or recut scenes in the previous restoration.
I've only watched the first disc, but I understand that the triptych is in widescreen at the end, which is why I suspect this might be the specific version rollotomassi described. While these discs are obviously not a professionally produced release, this version is still preferable to the butchered Coppola version out on DVD in some regions. But if it's true that the conflict has petered out and an official release is imminent, then it's probably worth waiting to see the film in as close to its original glory as possible.
