MythTV and repo conflicts...

My current repo list is the default fedora repos PLUS livna.

When I tried to install MythTV, I get this error:
Error: Missing Dependency: libmp4ff.so.0 is needed by package mythmusic

Some say that I need to disable livna, install atrpms repos, enable it, then
yum remove faad2

But if so, it would remove:

Egads!  This is literally all the work I had done to get all
of my sounds, music, videos support that works great right
now - I really don't want to have to lose hours I have spent
getting all that setup or to remove and pray that I can get
it all back in working order!

I have a Diamond XtremeTV USB 2.0 TV tuner (PC600) that
I would like to use - I wonder if it is worth it.

Any advice?

Thanks!
Dan
