Also, that smear mark looks like it's a gluestain, but not from a splice. It appears to be a torn frame that was patched back together. Normally you just cut these out, but I guess this one was small enough to be repairable.

Finally, as to disqualification of the (apparently) 16mm Catnap print, while obviously this isn't a "theatrical performance" (i.e. live from a theatre), this seems a bit harsh. Number one, none of the SW video bootlegs are from an actual theatrical performance as far as I am aware (unlike the audio recordings), they are just film prints photographed or telecined. You could argue that these prints represent what people would have been seeing on the screen, even though this doesn't actually capture that process live, but by the same token the 16mm is just a copy of these anyway, so it is virtually the same in a preservationist sense (at least when dealing with VHS quality). I realise there is a technical difference, but in a practical sense it is an "original 1977 film source", and I think that is the ultimate point of this collection, so if it does not qualify technically then it ought to qualify as a supplement.
