Found out what's going on, has to do with me transcoding hidef to svcd. The
original ATSC streams are
TeX font metric data
(\377\377\377\377\377\377\377\377\377\377\377\377\377\377\377\377\377\377\377\377\377\377\377\377\377\377\377\377\377\377\377)

Transcoded files are MPEG sequence, v2, program multiplex

This actualy works out pretty good for me as it's easy to see what's
transcoded and what's not.

file --version
file-4.16
magic data from /etc/magic:/usr/share/file/magic
