I JUST found my tape of Emmet Otter that I taped off of HBO in the mid-1980s. It's in SLP, (as I figured) but it looks remarkably good. Unfortunately- I accidently taped over the last few minutes of it at some point, long ago.

I also have a complete tape of the Nick version, (which is SP and hi-fi sound), but I noticed that there is a transition that is missing from the Nick version (because of the 1 commercial fade-in/out) that is present on the HBO version.

I think it's worthwhile (if possible) to edit in the transition from the HBO version into the Nick version, as the Nick fade-out is a bit clunky.

I don't know if anyone is still working on this, but I'd be happy to provide both of these versions, if you still need them.
