Since the scaler is not being explicitly set as a vfilter it will be
auto set to handle the material progressively. You *must* explicitly
define the downscaling as a vfilter with the -interl turned on...

Also note that by default the mxf will be tff and for DV you need bff so
that needs setting in your filter chain.
