[mythtv-users] force mythfilldatabase to update existing guide data?

[Paulo Fraser]

Hello,

I have noticed that some of my guide data is wrong.  The web interface of zap2it.com is correct but my Myth guide data is wrong.  Running mythfilldatabase manually gives the following

Channels updated..  Updating programs...
Data is already present for Mon Nov 15 2004, skipping

(other stuff edited)

The problem is that some of the data for Thu Nov 18 is wrong.  Specifically the time for the show "Long Way Round" on Bravo, Myth thinks it's on at 10pm it's actually on at 8pm.  I think that if I could just have mythfilldatabase update the existing data it would fix the guide.

I haven't found any documentation for mythfilldatabase other than --help which doesn't indicate anything that could force an update.  Except maybe:

--graboptions <"options">
   Pass options to grabber

but what are the options???

Does anyone know how to make mythfilldatabase update existing guide data?
