I noticed yesterday when experimenting with my new hdhomerun, that
when I change certain things while creating the card in mythtv-setup,
it gets inserted into the database twice with some differences in
settings. In mythtv-setup it only shows ones, but in the database and
in mythweb there are two. I have to look further into what exactly
causes this. I guess it's a bug and I then will file it.
