I have some code in my CVS now that changes the way tables are handled and
tracked.. Its almost working.. I had John test this in the UK and we are
picking them up now and its turned on on a NetworkID by NetworkID basis.. The
other problem is the LCNs that Juha has uses a different number of bits so it
will be fun to work this all out..  Too bad DVB didn't think of a "channel
number field".. Then again EIT doesn't have a "Subtitle" field either..

See I always had plans to do it.. :)
