The crux of this bug is that there are several stream type IDs that conflict
between BluRay and other standards.  The HDMV registration descriptor will only
be present in BluRay streams and thus will not be seen in my stream.  We use
the presence of this descriptor to determine whether we will interpret the
stream types as a BluRay type or "other".

The presence of DCII video is not indicated by a descriptor, but in the
"stream_type" field in the elementary stream loop of the PMT.  If you look at
the PMT (pid 0x35), you will see an elementary stream with a stream type of
0x80 (DCII).  If this were standard MPEG2 video, it would be a stream type of
0x02.

If you use the dvbsnoop utility (available on most linux systems), you can run
the following command to look at the PMT of my stream:

dvbsnoop -s ts -tssubdecode -if dcii_stream.ts -N 10 0x35
