Need help: avisynth + ffdshow doesn't work

[mod]

Hi all.
I've been using dgindex + avisynth + ffdshow a lot for editing with VDub, and with ffdshow decoding activated I've always been able to decode properly also with MPC and ZoomPlayer, just to have an idea of the final result before encoding.

The problem: in the last week, the avisynth files aren't decoded by any application that worked before, except VDub.
IMO the problem isn't avisynth because Mplayer can read .avs files well, and VDub with ffdshow support works normally.
Also WMP fails to open the .avs files.

Of course I checked every .dll used in the scripts, but also a simple DirectShowSource() fails..

I've tried uninstalling ffdshow, avisynth and the players, but I still can't get it to work.

I post here the output of MPC, hoping someone can get an idea:

The txt (@rapidshare): MPC_log.txt (http://rapidshare.de/files/23707984/MPC_log.txt.html)

Ideas?

ffdshow: May 22 2006 - GCC 4.0.3 sse, x86, ansi
avisynth: 2.4.6 and latest beta
players: MPC 6.4.9.0 , WMP 10 , ZoomPlayer Std 4.51

If asked I'll post the system specs

Any help appreciated!! :)
