Explain the reason in the commit message, e.g:
Some DVB and ATSC captures are using the official MPEG2 registration
descriptor in addition to using the correct stream type and the
AC-3_audio_stream_descriptor/AC3_descriptor. So let's add it even if it is
not strictly needed for DVB/ATSC.

"else" is not really needed, I'd rather avoid it for consistency with
similar code below.
+ put_registration_descriptor(&q, MKTAG('E', 'A', 'C', '3'));
Otherwise LGTM.
Thanks,
