Here's the script:
LoadPlugin("C:\Program Files\AviSynth 2.5\plugins\MPEG2Dec3.dll")
LoadPlugin("C:\Program Files\AviSynth 2.5\plugins\Decomb521.dll")
MPEG2Source("C:\Desktop/TRCS1E1.d2v, idct=5", ipp=true")
(Telecide("order=0, guide=1, post=0")
Decimate(quality=3)
I'm using Windows Vista so if I need to change something let me know. Added screenshot for reference
