[Selur]

LoadPlugin("G:\Hybrid\AVISYN~1\LSMASHSource.dll")
# loading source: C:\Users\Selur\Desktop\Los Bravos – Black Is Black (1966) .wmv
#  input luminance scale tv
LWLibavVideoSource("C:\Users\Selur\Desktop\Los Bravos – Black Is Black (1966) .wmv",cache=false,stacked=true,format="YUV420P8",repeat=true)
# current resolution: 856x480
return last

crashed with the file,...

LoadCPlugin("G:\Hybrid\AVISYN~1\ffms2.dll")
# loading source: C:\Users\Selur\Desktop\Los Bravos – Black Is Black (1966) .wmv
#  input luminance scale tv
FFVideoSource("C:\Users\Selur\Desktop\LOSBRA~1.WMV",cachefile="H:\Temp\wmv_7df0c91b391dcb28bda4362abecff8f2_32662_1_0.ffindex")
# current resolution: 856x480
return last

works fine here
I enabled 'Filtering->Avisynth->Misc->Prefer FFmpegSource" should fix the issue.

Cu Selur

Ps.: Funny thing is that LWLibavSource can handle the file fine when using Vapoursynth,..
