Thanks y'all.
Update: I got hold of what porports to be an "HD" rip of a streaming version of 'The Warriors: Theatrical Cut' but it due to heavy streaming compression, it's actually lower quality than the DVD (It's also slightly cropped and the colours are washed out). So it won't be used as a source for this HD project. Even for the brief sections where I need replace whole shots, the DVD looks superior to my eye (And that's before any sharpening is applied etc). It's a nice comparison refrence to have though.
For those interested here is a frame comparison...

It looks like I should be able to "reconstruct" every shot using a blend of the Blu-Ray and DVD. Like I did in post#33 ^. Because the additional zooms/pans are
digital, it's relatively easy to reverse them in most cases. e.g. If I line up frame No.1 of a shot, and I line up the last frame of the shot, all the other frames fall prefectly and mathematically into sync. Some shots where both zooms and pans have been aplied are little more tricky, involving animating the shot frame-by-frame, but still doable (So far). I've got the first 10 minutes completed
