So you don't know of any comparisons?
Are there really different wolverine / somikon / reflecta film scanners?
(Reflecta offers two scanners with very similar names)
I ask because you mention the "Pro" model.

Not if your goal really is a dvd: In that case, you don't want
interpolation and if you use MEncoder, you can specify the
input frame rate and output frame rate independently (and
you have to for soft-telecine).
