Virtual Dub won't open DV file

[benderrr]

Hi,
I grabbed a DV file form my camera using DVIO. Now I want to open it in the newest virtual dub. However, trying to open/video_file it says "Couldn't locate decompressor for format 'dvsd' (unknown)". I have the Panasonic video codec installed, however.
This made me think I have a type-1 DV file. Following the sticky thread, I wrote a script like
DirectShowSource("D:\blabla\dv_file.AVI")
and saved it with .avs extension. However, trying to open that script with Virtual Dub resulted in an error:
"Avisynth open failure: Unrecognized exception!"... line 1
This happened on 2 different computers.
What's going wrong here?
Thanks in Advance,
bender

Welcome to the forum, benderrr.

Maybe your Panasonic DV codec is not properly installed. Try to install another DV codec to see if the problem vanishes.

In the DirectShowSource command you should specify the framerate, like
DirectShowSource("D:\blabla\dv_file.AVI", fps=25)
If you're in NTSC land, you'll probably use fps=30 instead.

If DirectShowSource doesn't work at all with your DV file, there might be an issue with the MS DV DirectShow filter (which you should have installed already).
