GK Access violation

[hdi20]

I keep getting the "Access violation at address 7C93426D in module 'ntdll.dll'. Read of address 241F2321" error message (see attachment). Message appears after I open *.avi file with GK. Could it have anything to do with DVD Shrink or DVDFab, since there were no errors before I installed those programs.
I need a quick solution, movies are piling up and I'm running out of disc space.

win xp pro sp2
GK 0.35.0

What are those AVI files? Please render them in latest GSpot (2.52) using native decoder and not MS rendering and see if that's working. If not - GK will not be able to open such files directly (but avisynth might).

This is what gspot reports.
Its not that GK always crashes when opening such file, somethimes it crashes while I'm adjusting output resolution or when I choose save&encode.

Try different hyffyuv decoder...
