I did notice the reenforcing of the vocals. I've only watched Under The Sea at the moment. Like I said before, compared to my first release VHS, the vocals are heavily enforced, and didn't blend like they did on the tape at the end. I've long be an ardent believer in original sound mixes. I was quite peeved that they didn't include it here.
I also noticed that my TV didn't like the reds. Though I'm well aware of the fact that it does have a bit of the chroma bug, it varies from source to source. It hit the DVD bad, but not the VHS oddly. I still need to look at that Old DVD rip to compare whether any color correction occured. I just don't remember her tail being that green. I actually used to use the tape back in the day to calibrate the tint on my old TV.
As for anyone willing to do it, I might be able to. I say might as I've never done anything like this before, and until your post figured all I had to really worry about were some knees and what should be a simple audio switch. That. and I'm not entirely sure if this would constitute as a legitimate preservation project. I do love the film enough that I might be able to at least attempt this for experience. I'd need to clear more disk space on my HDD to fit a rip of the two DVDs first though. That, and look into how to do the points you've made. If anything, it'll help me gear up for helping my friend restore a fanfilm he made a decade ago.
