I've written a plugin to help deal with interlace problems. I'm making it freely available.
It allows the fields to be treated separately. Fields can be blanked, copied to the other field, interpolated into the other field, and swapped.
The fields can also be separated into upper and lower halves of the frame to allow for individual processing and the halves can then be recombined back into the interlaced frame.
There is also a 'blend' slider to set the amount that the effect is applied.
