Please help me figure out how to fix this horrible Clear Vision release!

[Bum_Rush]

I recently purchased Spider-Man the complete 1994 animated series from Amazon UK. It is a Clear Vision release. No US release was available so this was the best I could get. I received it a few days ago and am really frustrated at the quality of this release from a major company! I have read that some of their other releases were bad for previous series, but the few reviews of this one were decent.

I have been pulling my hair out trying to figure out how to fix a few issues I have never enountered before. And I don't even know for sure what are the proper names of the issues I'm having. I think this release has dot crawl or aliasing issues, or something! And of course it has rainbowing and noise problems as well.

Basically the biggest thing I want to fix are these annoying "dots" that flicker / flash rapidly along edges. On some straight lines they are clearly visible, but they also appear in other places. Is this dot crawl? How can I get rid of it? I have tried avisynth scripts like Checkmate and they don't seem to help at all. Also, the credits are a rotten mess. Edge dots, shaking lines, and rainbowing all. How can I tackle this?

Please see these sample clips. They are .m2v files extracted directly from DGIndex. Of course the original frame rate is 25fps PAL. I was using avisynth with QTMPG and SRestore to restore them to 23.976, but all of the dots and flickering remains.

(Please look at Spider-Man's back just a few seconds in. Make it full screen. Rapid dots moving like crazy!)

Clip 2: http://www.mediafire.com/?1t22eos1m13ivzk
(Please look at the window edges. And the picture frame in the next scene. All have crazy moving dots I can't get rid of. And this clip also contains the end credits that are a complete disaster..)

Thank you to anyone that can help. I really tried reseaching this for days before I posted. I have tried many scripts. I just can't get rid of these dots!

The mosquito blocking is part of the encode and can be caused by a few factors:

1. Source is likely NTSC converted to PAL.
2. Low bitrate on encode, likely many episodes on disc and needed to be squeezed to save space.
3. Crappy encode. Compressionist having a bad day!

Clearvision usually do a good job on the encode, so I suspect it's factors 1 and 2.

Yes, it's pretty clear this was made from an analog NTSC source through a standards converter without a 3d comb filter between them. The NTSC dot craw artifacts were scaled and field blended along with the rest of the picture. Then you have MPEG compression artifacts further enhancing them. It's going to be hard to remove them. The usual dot crawl filters will not work.
