Problem with audio sync when deinterlacing

[araset]

Hi when deinterlacing AVI file with Bwdif (Avisynth) (also tried vapoursynth) audio runs out of synch. AVI file plays fine.  I can't upload the whole AVI file because it's very big and on small sample it's ok. It only happens on the big file. Thanks for every help.

ffmpeg reported on audio extraction reported "time: 03:22:52.20", but Hybrid assumes a length of 12172.2 s for the video which would match that length.
Don't see any errors in the processing, so my guess is that either the source filter has a problem, or the source if vfr.

1. Does it make a difference if you use AviSource as source filter?
(Enabling "Filtering->Avisynth->Misc->Source->Prefer AviSource for avi input" will prompt Hybrid to use AviSource, assuming you got 64bit vfw decoders installed in your system.)
2. Does enabling "Config->Input->Decoding->CFR output" make a difference?
