Doing so requires choosing a grabber with exactly the same capabilities 
as tv_grab_it.  Since the different grabbers all have different 
capabilities, mythfilldatabase has a lot of code that makes decisions on 
how to run the grabber based on the grabber's name.  This approach is 
difficult to maintain, and makes adding new grabbers impossible for 
users who don't compile MythTV, thus the work Stuart is doing with 
tv_find_grabbers/XmltvCapabilities.

In the case of tv_grab_it, it looks like tv_grab_no is the closest 
match, but there's a 6-hour offset that would totally mess up the 
listings for tv_grab_it.  The other close match, tv_grab_de_tvtoday, has 
an option "--slow" that would cause tv_grab_it to retrieve a different 
web page for each program in the listings.

It looks to me like the most-workable non-compiling approach to using a 
new grabber is choosing "No grabber" and using a cron job with 
XMLTV/"mythfilldatabase --file".
