(you can see it somewhat at the bottom left)

It's actually worse when you watch the video, and it's pretty
annoying. What could cause these fuzzy edges?

At first, I thought it was a cropping problem. I played around
with the crop values for a while, but the edges were still there
every time I encoded. I then started playing with the resize
values, again to no avail.

This is my script:
---------------------------------------------------------------------
LoadPlugin("C:\PROGRA~1\GORDIA~1\mpeg2dec3.dll")
LoadPlugin("C:\PROGRA~1\GORDIA~1\decomb.dll")
LoadPlugin("C:\PROGRA~1\GORDIA~1\UnDot.dll")
LoadPlugin("c:\progra~1\gordia~1\avisynth25\asharp.dll")
LoadPlugin("c:\progra~1\gordia~1\avisynth25\TemporalCleaner.dll")
LoadPlugin("c:\progra~1\gordia~1\avisynth25\Deen.dll")
LoadPlugin("c:\progra~1\gordia~1\avisynth25\aWarpSharp.dll")
LoadPlugin("c:\progra~1\gordia~1\avisynth25\MSharpen.dll")
LoadPlugin("c:\progra~1\gordia~1\avisynth25\Unfilter.dll")
mpeg2source("F:\DVD\Projects\cb1\cb1.d2v")

Telecide(order=1,guide=1).Decimate()

crop(6,0,708,480)

TemporalCleaner()
deen("a2d",2,10,12)
LanczosResize(640,480)

Undot()
aWarpSharp()
---------------------------------------------------------------------

Any ideas?

If the black bars are in the encode, leave them out next time. this also will save some bits.

Since this is a cartoon, you might also want to try a matrx which cuts a little more the high frequencies (higher values in the lower right corner). But I am not an anime extert.

BTW I don't understand why people are using Lanczos, because it does not up- or downsample sooo much better. Instead it artificially sharpens the image a bit, which you can also do with bicubic. Just make the test. Make some screen shots from your source, the one half upsampled with lanczos the other with neutral bicubic, and then compare.

I have to disagree with ObiKenobi and say that aWarpSharp is probably the cause of your problems. It doesn't like edges.

I just did a little testing, and found out that aWarpSharp was indeed
the culprit. I never would have guessed it. Thanks for the help.

Use Guavacomb and/or Mipsmooth to kill those rainbows!
