Crash DVD encoding and Vapoursynth

[Devilman1]

I try to encode a DVD to mkv and as usual I use vapoursynth and x264, but it crashed when it starts the 1st pass. I don't have this problem when I'm encoding blu-ray.
I haven't applied any filter or crop to the DVD, only mkv tagging for audio and subtitle that I already extracted and converted to srt.

If I try to test the script I receive an error message, but I have the same problem when testing script of blu-ray.

It's a new installation of Hybrid from scratch that I'm using.

Thanks
