Dark/Sega has pulldown frames stored in YV12 space, so after IVTC you'll find some combed chroma like Moth3r described.
That's why I chose selectEvery(10) in my IVTC scripts for those
instead of using selectEvery(5) a.k.a. pulldown().
That way the telecine 3's can avoid the problem, however half of the 2's are still affected no matter what.
So every fourth frame in the progressive stream will be suspect.

Thanks for the information, Darth Mallwalker!

Do you know if DJ captured in YV12?
