No interlacing shouldn't matter. Did you make sure to put converttoyv12() in your script? Many filters including chubbyrain2 and gradfun2db/mod are only compatible with YV12 and don't work even with YUV (which is the interleaved equivalent and often the colourspace supplied to Avisynth). If you want to keep 100% quality (i.e. the full luma quality) you could try doing this:

pointresize(width(),height()*2)
converttoyv12()chubbyrain2() #or gradfun2dbmod()
converttoyv16() #or converttoyuy2()pointresize(width(),height()/2)

Also, I suggest using AvsPmod instead of VDubMod which is obsolete now. For the credits if they're all black-and-wite you could just convert that section to greyscale using greyscale().

Finally got some decent results. Removed a good portion from what I can see. The next issue would be ridding the video of the haloing & more crosstalk. I understand that I'd lose detail, but I'm trying to make a better master. Any suggestions?

Here's an example of what I believe to be crosstalk?:

Here's a sample (YV12 AVI) of the clips with the most chroma crosstalk, can anyone give a basic script an attempt and see if it's salvageable?
