Problem with Avisynth and Zarxgui

[Mitsukai Mizu Amaya]

I've tried exporting my AMV for a contest, and I'm having the following problem:
it's exporting at 720x960, instead of 720x480. It's also half the length it should be, like it was sped up or something.

My Avisynth Script:
#ASYNTHER AVISource
AVISource("C:\Users\Scarlet\Desktop\Scarlet
\AMVs\XSAMV.avi")
converttoyv12()
Deen("w3d",3,3,5)
FRFun7(lambda=1)
LimitedSharpenFaster(strength=100)
LanczosResize(720, 480)

The other three came out fine, and this one looks fine in VDub, but what the hell? >> Help, please? D8

You open that script in vdub, and everything is fine, but you encode it and it gets all messed up?
How are you checking the encode?
Load the encoded video into avisynth via ffvideosource and see if the problem is there.

Not implying problems with incorrectly set aspect, but incorrectly set aspect. Alternatively possible broken interlacing! Could also be a layer 8 network error in your video upload/playback setup.
