It looks like there are some 1080p up-scales on youtube.

Perhaps, up-scaling the DVD video with Video Enhancer (Super Resolution) and then using some sort of dust / scratch removal software, like Neat Video, might be an option for restoration?

I have no skills to make this happen but I would love to support such an effort.
