VirtualDub unable to open avisyth scripts

[JeanMarc]

OK, I am getting really frustrated. I have been using VirtualDub/VirtualDubMod and avisynth for years, and processed hundreds of videos but today, I am stuck. I suspect the problem comes from my recent installation of MediaMonkey, PS3MediaServer and the CCC codec pack.

I was before using the K-lite codec pack. I have spent a lot of time searching the web, Doom9, the VirtualDub forum, VideoHelp. No solution so far.

I have un-installed and re-installed (several times) avisynth 2.5.85, VirtualDub 1.9.10, VirtualDubMod, the K-lite codec pack, ran CCleaner, rebooted.

I am at the same point: I can't open even a very simple avisynth script with VirtualDub, such as:

DirectShowSource("L:\MyVideo.avi").

(What I am really trying to do is run

MPEG2Source("L:\MyMpgVideo.d2v")

but I am trying to do something basic at this point.)

When I try to open it with VirtualDub, the VirtualDub window opens for a fraction of a second, and closes. With VirtualDubMod, I get the error:

AVI Import Filter error: (Unknown) 80040154

On the other hand:

• Media Player Classic can run the script, as well as Windows Media Player and apparently other applications (I ran HcGui), which tells me that avisynth seems to work normally.
• At the same time, VirtualDub or VirtualDubMod can open and play the video directly.

So it looks like the only type of file VirtualDub doesn't like is the avs script, and the only application that doesn't run the avs script is VirtualDub.

The problem is that I installed, configured these applications with all the plugins I needed 3-4 years ago, and I am not able to go through the same exact process any more.

I tried to run VirtualDub with minimum plugins, no success.

I would REALLY appreciate any help. I love VirtualDub, and I think I need it to edit my avisynth scripts prior to encoding.

Thank you.
