I've actually found that there's a lot less judder doing it this way
than to normal interlaced 29fps, particularly with high speed images
(which is what 90% of what I shoot and edit is). The interlaced PAL is
auto-deinterlaced in the conversion process.
But if your only option is a software conversion exported from an NLE
then it's a better solution than to 29fps.
It's not the perfect way to do it by any means, but if you don't have
access to, or can't afford to do it the way TV broadcasters/program
distributors do it, then it can be an acceptable solution - certainly in
the context of the original question, anyway.
I'm very interested in this Avisynth that you recommend, but sadly their
site's down at the moment.
