MXF is mostly used in the post-production industry, avid etc.
The new file-based camera disks from Sony, JVC, panasonic etc use
this format. It's not that widely accepted yet (avid doesn't
support it natively yet, they supply a conversion tool).

Having MXF in gstreamer would be a very good idea, it would be
accepted and used very fast by automation companies.
Having this avid opensource HD codec in gstreamer might also be a good idea:
