I can see one way to implement this, but *only* once bug #703884 has been
implemented.

Once the logic in that bug has been handled, you would then only have to:
1) if more than 100ms (or more) has gone by without a PAT, assume that the PAT
is indeed missing
2) For each of the pending PSI/SI streams, check which ones are potential PMT
(table_id:0x02). If you have one use that PMT to initialize the program (and
carry on as normal)
3) If you haven't found a PMT... you'll have to expose all PES streams
4) For each pending PES, you'll need to pass the data through the typefind
functions to figure out what the nature of the stream is. If you have a very
high probability match, use those caps and expose the stream
5) If you don't get a very high probability, it might be because we don't have
a typefinder for that (might want to create one) or that we don't have enough
data yet to typefind it.
