Of these Myth uses the short_event_descriptor &
extended_event_descriptor. I'd be interested in seeing a copy
of your dvbsnoop logs for reference. (email me this privately)

You should start in eitfixup.[cpp|h]
This is where all the fixup routines live.
You will need to determine the NetworkID for your provider and use
that to trigger the fixup.
Looks at some of the existing routines for inspiration.
The UK fixup is used to build good title / subtitle & description
data from just a title & description.
I'm normally on IRC in #mythtv on freenode if you have questions.
