drngr: OK, I busted-out some manual IVTC action. I used DGIndex to generate the d2v and chose "Honor Pulldown Flags".

It, again, found the field order transition errors and I told DGIndex to fix them. I then used the fixed d2v (rather than the d2v.bad) and did my manual IVTC.

I used IsCombedIVTC (from TIVTC) with ConditionalFilter to check for residual combing (indicating a pattern break) and told it to output a red-colored frame whenever it detects any.

I'm not seeing any red-colored frames with the fixed d2v, but I see lots with the d2v.bad.

Here's my short script: http://pastebin.com/5UCZcPq1

Please execute it and let me know if you get the same results.
