When EIT data collection is enabled in MythTV, the scheduler re-runs 
every 5 minutes--and EIT will constantly overwrite any changes you make 
to the data in the database.  Therefore, what you should be doing is 
using something other than MythTV EIT data collection.

Specifically, what I'd suggest is to use the current EIT-to-XMLTV 
processor (no idea which one is the one you're supposed to use these 
days) to grab the EIT data, modify the XMLTV data as desired, then use 
mythfilldatabase to insert that data into your database.  You can create 
a script using, for example, the Python bindings to determine when is a 
good time to do the EIT collection, then "check out" a tuner for use in 
collecting the EIT data, then run mythfilldatabase.  With this approach, 
you control not only when EIT collection and rescheduling is performed, 
but also--through editing the content of the XMLTV data file--you can 
control the information in the listings.
