[mythtv] Feature Request: Starring

[Villa Sara]

Okay, I've searched the MythTV mailing lists and I didn't see that
anyone else has brought this up so...

Is it possible for MythTV to take advantage of the "Starring" field that
Zap2It uses for some of their listings?  I know searching for shows
based on who's starring is one of the few things that Tivo can do that
MythTV can't (for now).

Is this something that MythTV can do via mythfilldatabase, or does it
take a fundamental change in xmltv?  

I'm not a programmer/coded/hacker* so I don't know the answer to this
myself.
