My script is:
LoadPlugin("C:\Program Files\AviSynth2.5\plugins\MPEG2Dec3.dll")
LoadPlugin("C:\Program Files\AviSynth2.5\plugins\Decomb521.dll")
MPEG2Source("C:\Documents and Settings\Everybody\Desktop\Code Lyoko\Disc 1\VIDEO_TS\Zero Gravity Zone.d2v", idct=5)
The screen shot below is the error and the step I am on in the guide (for those of you who are familiar with it.)

Can anyone help me?
