Honestly, I don't know what half of that stuff in the AVISynth script is 
about, but there is a comment line in there about cleaning up a 
"blocky/noisy" mpeg2 source. That sounds like a job for the hqdn3d 
filter (high quality denoise 3d). This filters image noise in both 
spacial and temporal domains. There are also horizontal and vertical 
deblocking filters (pp=hb,pp=vb). pp=de will give you a default 
deblock/dering filter set.

I've no idea what kind of output file you are trying to create, so this 
example just uses default settings for lavc encoders. You can get much 
better results by reading the manual and following the examples. (for 
example, by specifying the codecs you want to use, codec options to 
optimize size/quality how many CPU threads to use, etc.):

mencoder INPUT -vf pp=de,hqdn3d -oac lavc -ovc lavc -ffourcc DIVX -of 
avi -o OUTPUT
