Yes, that was my first feeling, that a dissector would be best.

I was told on the Wireshark mailing list that that particular dissector was
not incorporated due to outstanding bugs.  I didn't continue to research the
issue and have no idea how severe the bugs are.  Here's another post from
the same author that told me about the problems.

Another drawback is that it doesn't decode MPEG4 TS.

Thanks for the suggestion,
