Hm, if I have a backup, I don't know where it is.

There are too many channels to do it manually. Is there some
documentation about the database design?

It seems to work fine so far, and some dead data in the database won't
really matter. But it bothers me ... and it could cause problems after
some time which then would be hard to solve.

What if I just delete all tables or the whole database? Will it/they
be recreated when running mythtv-setup?
