The main part that is needed is support in DVBStreamData (in
libs/libmythtv/mpeg) (just a few lines of code). But before
I enable this, we need to address the issues in #1485. The
old SIParser scanner wasn't always saving the correct NIT #
in the tuning tables. At the moment this isn't a big deal
because we aren't using the NIT values for tuning. But, when
the new scanner is working properly it should be saving this
information correctly, so it should be safe to monitor the
NIT and SDT. Or at least optionally; monitoring these will
slow down tuning about 50 milliseconds on average so I will
probably make the current, PMT only, based tuning selectable.
