VirtualDub / Avisynth setup problems

[Busty]

Hi everyone,

I hope someone here can help me figure out what is wrong in my setup.

I revived an old installation of AviSynth 2.6 and VirtualDub 1.10.4 and fail to open an AviSynth script in VirtualDub. It did work when I used it about 8 years ago, but now it doesn't. This installation is on a MacPro running El Capitan, done with PlayOnMac following l33tmeatwad's instructions from about 2016, in case that matters.



VirtualDub does open the version test script as described here: http://avisynth.nl/index.php/First_script

I can open the video with drag and drop into VirtualDub.

When I try to open an AviSynth script, VirtualDub stops responding.


I tried scripts like these:

AviSource("c:\folder\myclip.avi")

and

DirectShowSource("c:\folder\myclip.avi")

(I created the according folder and put the video in there)


My only idea is it might be an AViSynth codec issue. How can I check which codecs are installed for AviSynth? Or does anyone have a more indepth idea of what might be the problem?
