At the moment I'm trying someting with pixiedust (noise filter), eedi2 (to remove the jaggies) and 2 sharpening filters (limitedsharpenfaster for overall sharpening and fft3d for edge enhacement). Well, it's not a final version, schorman13 but here's what I have so far:

Loadplugin("dgdecode.dll")
MPEG2Source("Star Wars.d2v")

converttoyuy2
Loadplugin("loadpluginex.dll")
loadplugin("dustv5.dll")
PixieDust(limit=1)

loadplugin("eedi2.dll")
Crop(6,102,-2,-104,align=true)
eedi2()

loadplugin("fft3dfilter.dll")
FFT3DFilter(bt=-1, sharpen=0.6)

Loadplugin("mt_masktools.dll")
Loadplugin("warpsharp.dll")
Loadplugin("removegrain.dll")
LimitedSharpenFaster(dest_x=720,dest_y=360)

Addborders(0,60,0,60)
Converttorgb

I included the loading of the plugins in the script so you know what dlls are required.
