This is quite unusual compared to other EIT data.

You have modified siparser. Sadly it is no more.
You will need to rewrite this patch for svn head.

There are a few things that come to mind.

1) Normally the EIT data provides us with title, subtitle & description
in some form, that can be processed into a form suitable for myth.

2) For the EIT we use a Fixup routine which is normally keyed off the 
networkid, which does the processing mentioned in #1.

3) You will need to implement some sort of fixup that uses the extended
event information to "improve" the data initially received.

Please ask if you have further questions....
