Muxing interlaced video

Can't reproduce this here with any of the sources you shared.

I did not upload the file that causes this bug.

Okay,..
I could reproduce the 'preview closing'-issue (I hope) by:
1. disabling deinterlacing
2. setting Support to Avisynth
3. disabling 'No Avisynth during Preview'
if I then
- use the Preview: no problem
- use the Filterview: preview doesn't work

Looking at the Avisynth script:

LoadCPlugin("I:\Hybrid\32bit\AVISYN~1\ffms2.dll")
SetFilterMTMode("DEFAULT_MT_MODE", MT_MULTI_INSTANCE)
# loading source: C:\Users\Selur\Desktop\Slipping Through My Fingers.mov
#  input color sampling YUY2
#  input luminance scale pc
Source = FFVideoSource("C:\Users\Selur\Desktop\SLIPPI~1.MOV",cachefile="E:\Temp\mov_168a0fcc4b78793dc3cfc53d9480d544_853323747_1_0.ffindex",colorspace="YUY2")
# current resolution: 768x576
# filtering
Source = Source.AssumeFrameBased().SeparateFields()
# scaling
Source = Source.Spline36Resize(768,576)
Source = Source.Weave()
SourceFiltered = Source
SourceFiltered = SourceFiltered.AssumeFrameBased().SeparateFields()
SourceFiltered = SourceFiltered.Spline36Resize(768,576)
SourceFiltered = SourceFiltered.Weave()
# stacking horizontal for filter preview
SourceFiltered = SourceFiltered.ConvertToRGB32(matrix="PC.709")
Source = Source.ConvertToRGB32(matrix="PC.709")
StackHorizontal(Source, SourceFiltered)
PreFetch(8)
return last

the problem is that the resizing should only use 288 instead of 576.
-> I'll look into it.
