Multiple issues

[Selur]

1. DVD input now shows nothing in "Filter View"/"Crop View" with Vapoursunth,

Probably something I broke with the last changes.
Will look into it after work.

in "Avisynth" it shows just "Player", that plays stream, regardless De-interlace use.

That is correct. Crop and normal Preview do not use Avisynth at all.

2. QTGMC (Avisynth) de-interlacer disappears in the DVD input mode
(I tried replace mencoder/mplayer with the newer version as before - doesn't help)

That is correct. If you want to use Avisynth for DVD Input you need to enable "Config->Internals->Avisynth->Avisynth for DVD input".

QT Prores now shows in Vapoursynth "Filter View" promptly, however after assign "Despot" - "Filter View" becomes unresponsive, filtered result not showing.

Will look into it after work.

QT Prores "Dehalo"/"Dehalo_alpha"/"BlindDehalo3" shows some kind of mask even with "Show Mask:None"

Probably some issue with the color space handling.
Are you using Avisnyth or Vapoursynth here?
Will look into it after work.
