I found I've never had a need for any other Deinterlacers beside VDub's internal one, and Deinterlace - area based (with edge detect set to 0 to really catch all the interlacing lines): http://www.guthspot.se/video/index.htm

Any other ones just weren't sharp enough. Especially those ones beside IVTC that promise you to "restore progressive frames" after your footage has been interlaced in post do nothing but crap. Remember there's a difference in motion blur whether you capture your footage at 24p or 25p on the one hand, or 50i or 60i on the other. That's why it's crucial whether you're using spatial interpolation (that doesn't change your motion blur) or temporal blending (that exactly doubles it), because most of those that promise you to "restore" your progressive frames end up using nothing but temporal blending, even if they claim being adaptive, and that looks utter crap on footage that originated as 24p and 25p because the result equals a standard motion blur of 12fps.

Especially in PAL, you should consider first trying Field Reorder: http://home.earthlink.net/~tacosalad/video/fldorder.htm Up until the 1990s, it was common for terrestrial PAL airing to interlace progressive footage by delaying one field in relation to the other, so this filter, while not being a real deinterlacer, will take care of that better than any other.

And there *CAN* be a need to deinterlace progressive footage, in order to remove artifacts on borders that result from prior oversharpening without unnecessarily blurring non-affected areas too much.
