Plugin wouldn't load in Avisynth script?

[storebror]

Hi. Got a Avisynth-script that look like this and
Line 3 is suppose to add subs to the movie but how can one load
a plugin that's for VirtualDub and not for Avisynth?? At least that's the errormessage i get when i try. Got this from an Online Tutorial and the script Rocks except that line..

AVISource("D:\movies\The Jackal\The Jackal.avi")
LoadPlugin("D:\Program\Avisynth\plugins\mpeg2dec3.dll")
LoadPlugin("D:\VirtualDub\plugins\textsub.vdf")

AssumeFPS(25.0000,True)
BicubicResize(688,352,0,0.6,0,0,720,368)
AddBorders(16,112,16,112)
TextSub("D:\movies\The Jackal\The Jackal.ssa")
#Trim(0,179119).FadeOut(150)

There's a special command to load VirtualDub plugins: LoadVirtualDubPlugin

See http://www.avisynth.org/AviSynthPlugins
