I don't have either. But, I know that Grapevine released a VHS of the Nth Commandment years ago. As for Die Flamme, I saw the reconstruction last year during a Lubitsch retrospective. There is very little left of the film, about 20 min. It's patched up with lots of stills and titles. More details here. (click the Google translate tool for an English translation)
i reallly hope flicker alley realeases fragments, it would be a shame not too and if they happen to throw in a fe extras thats would be fine with me like maybe a restored KEEPER OF THE BEES trailer
