[mythtv] EIT table parser

[Chris Birkinshaw]

A couple of questions about the table parser:

1. It seems to only start when the backend is recording - is this correct? If so
why? It caused me problems recently when the machine had been off for a few
weeks.

2. Which sub-tables does it look at from PID dec 18?

And some info:

In the near future the system which produces the DVB SI for the UK network will
receive triggers from the program providers at program junctions. For example:

Now: 10:00 Sport
Next: 10:30 Weather Update

If the Sport overruns and a trigger is not received until 10:34 then the EIT for
this service will not change until 10:34, at which point it will become:

Now: 10:30 Weather Update
Next: 10:45 Something else

And the table version number will be incremented.

If mythtv were to hold off recording until the scheduled recording event became
the EIT "now" event then it would always start recording exactly at the correct
time.

Its worth mentioning that this is currently the case for the EIT"actual" (i.e.
for originating transport) for multiplexes 1 and B (would allow testing) but
not the case for the other multiplexes EIT"actual" or the EIT"other"
cross-carry SI information.

Food for thought...
