Well splurged for a new computer! (2.4 GHz Pentium IV )
With this however involved alot of software re-installing.
Now I come to this problem

" Avisynth open failure: Unrecognized exception!
C:\Video\Work\Austinpowers.avs, line15)"

when I try opening the following script in VirtualDub:

#=============================================#
# -= AviSynth script by MovieStacker v1.1.1 =- #
#=============================================#

LoadPlugin("C:\Video\MovieStacker\Filters\MPEG2Dec .dll")
LoadPlugin("C:\Video\MovieStacker\Filters\Temporal CleanerOld.dll")
LoadPlugin("C:\Video\MovieStacker\Filters\GripFit_ preview.dll")
LoadPlugin("C:\Video\MovieStacker\Filters\BlockBus ter.dll")
LoadPlugin("C:\Video\MovieStacker\Filters\DustV5.d ll")
LoadPlugin("C:\Video\MovieStacker\Filters\LegalCli p.dll")

AviSource("C:\Video\Work\austinpowers.avi")
ConvertToYUY2()
LegalClip()
GripCrop(352, 480, overscan=1, source_anamorphic=false)
GripSize(resizer="BilinearResize")
SpaceDust()
TemporalCleaner(ythresh=5, cthresh=10)
BlockBuster(method="noise", detail_min=1, detail_max=7, variance=0.5, seed=1)
GripBorders()
LegalClip()

=========================

I am using Avisynth 2.08. Script works if the GripFit_preview statements (GripCrop, GripSize,GripBorders are eliminated)

Did a forum search only saw one problem like mine however it was never answered.

Any ideas.
Thanks
Patiently waiting to finally encoded .........

If the problem is related to GripFit_preview, uncheck that option on MovieStacker, and use the standard resizing method. The problem is probably related to the resolution of your AVI.

Thanks for the reply kwag

Good to know that the problem was with the source and not with setup, as you suggested.
