Thanks for responding.

How do I know if I have the mythfilldatabase issue solved? I can see the
actual program data when selection Tv/Schedule Recordings/Program Finder.
I am just concerned that it **always** says 0 replacements, which might be
fine.

I did complete all 4 steps of the setup program.

Thanx for letting me know about not running mythtv directly. Still
mythfrontend doesn't work as expected too (see above).

Cheers,
Mariano
