[HELP] Trying to remove VHS dropout (comet tails)

[Miranda]

I've already used KillerSpots in Vapoursynth which removed a lot of the spots, but not all. 

For a second pass, I have also tried switching over to Avisynth and using the additional settings in DeSpot, but I can't seem to get it to remove the remaining spots. 

Any suggestions?

There is also some additional noise on the whole video frames which I am unable to remove - it looks like a strange moiré pattern?
