The improvements to the captioning system and the transcribe feature are great, but for broadcasters (this one, anyways) exporting an MXF file with closed captioning encoded doesn't seem to produce the desired effect on air.

For instance, a file we get from another source says the text stream is encoded as "A/53 DTVCC Transport", whereas anything I export out of Premiere says "Ancillary data/CDP" and doesn't seem to translate to closed captioning in our broadcast. The option to select DTV captioning and ensure that a file is broadcast ready would be amazing.
