[HELP] PAL VHS capture issue

[Miranda]

One particular tape I captured recently seems to have a problem when de-interlacing to bob - it seems that during some scenes the frames flow one frame forwards and one backwards , instead of all frames flowing forwards naturally, and this makes the footage look jerky. I've not seen this happen with any other footage I have captured - any suggestions?

Sounds like the field order changed, what happens if you change the scan Type?

I did try changing to odd, but same problem.
