yeah, the problem is the question: is it invalid non-packetized
storage of a standard format (mpeg4)? or is it valid storage of a
stupid nonstandard format (xvid)?

it might be possible to write a sane rule to make it illegal, but i
don't know what to do since it's obviously brain damaged and should
never be used..
