Multiple issues

[serg]

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.

QT Prores in "Avisynth" "Filter View"  shows just "Player", that plays stream, regardless De-interlace use.
There is no way to assign any filter in Avisynth and preview it.
