I need to change DV-AVI type II files from 720x480 to (f.e.)352x240.

I'm using capturing with Pure Motion or MSP6 VidCap.
Vitual Dub can't open DV-AVI files.
I can't get AviSynth to work properly:
I've tried AVS :
DirectShowSource("c:\temp\video\captura\seba15B'20 010709 15.42.54.avi"
I can see the video on WMP , but I don't get any sound (?).
I can feed .AVS file to VDub. But Vdub can't save DV-AVI type II (or yes?). And no sound too.

(TEMPGenc 12i crashes when I try to load this .AVS)

How can I convert from DV-AVI type II to same type with different size????

Thanks for your VCDhelp!
