[mythtv-users] V31, switching to xmltv on fedora

[DaveD]

Fedora packages don't create a mythtv user in the usual sense: there is 
no /home/mythtv directory.  mythbackend runs as user mythtv.  I assume 
it spawns mythfilldatabase as the same user. Where is the xmltv data 
going to go?  Where does the channel setup data go?  I'm confused.  All 
the pages I've read so far keep referring to mythbuntu and creating a 
mythtv user.  Do I need to do that so I can run xmltv config as that 
user?  Other stuff suggests running xmltv setup (and mythfilldatabase?) 
as any user, then creating symlinks, again to /home/mythtv/.mythtv.  Do 
I have to have /home/mythtv/.mythtv for this to work? Would I be advised 
to create an actual profile with password and literally log in as mythv 
to run this stuff?

In a more general sense, why do I have to do anything?  Mythtv has been 
filling my database for years.  So now there's a new format for the same 
data from the same source for the same channels already in my database.  
Why do we need to do anything? Couldn't one write a script to do this?  
Or, better yet, add some code to the existing program(s) to do it?
