  Just to make it clear -- I don't care how industry names things,
  but the fact that these 3 flavors of DV have the same picture encoding
  algorithms with small amount of knobs designed to address bitstream
  constraints and differences in sampling -- make them all just a DV
  codec in my book. Now, I do understand the convenience factor of having 
  them as separate codecs -- but lets not be confused by the ffmpeg's
  current restrictions.

  Now, DVCPRO 100 is, in fact a different CODEC regardless of the name
  being similar to the DVCPRO 50.
