CCE crashing when loading script w/xvid

[luders]

The script works everywhere else but not in CCE. Other scripts work fine that dont use XVID files as far as I can tell. When I try and load the script it gives me "The instruction at "0xffff0069" referenced memory at "0xffff0069". The memory could not be "read".
Here is my script. I am using CCE 2.50 in Windows XP running it under Windows NT 4 compatiblity mode.

a=avisource("movie1.avi", false)
b=avisource("movie2.avi", false)
c=avisource("movie3.avi", false)
v=(a + b + c)
return(v).LanczosResize(640,270).AddBorders(0,45,0,45).LanczosResize(704,480).ResampleAudio(44100)

Any Ideas? -Aaron

Well I was using AviSynth 2.08 and I gave AviSynth 2.5.3 a try. That combined with using DirectShowSource instead of AviSource made it successfully load into CCE 2.50. However, after encoding, the playback was slowed down so that the video was in super slow motion.
Here is my script.

a=DirectShowSource("movie1.avi", 23.976)
b=DirectShowSource("movie2.avi", 23.976)
c=DirectShowSource("movie3.avi", 23.976)
v=(a + b +c)
return(v).LanczosResize(640,270).AddBorders(0,45,0,45).LanczosResize(704,480).ResampleAudio(44100).ConvertToYUY2

Perhaps I just dont know what I am doing since this is the first time that I have used DirectShowSource rather than avisource. I would normally check out the AviSynth manual at avisynth.org but the site is down. Any help? -Aaron
