[mythtv] WG: Bug when switching channels?

[Pferdekaemper, Thorsten]

> Hi,
> I had some problems switching the channels. First I thought that this has something to do with V4L/V4L2. But it simply seems to be a problem in the settings. You can choose which field in table channel is used to describe the channel. It seems that there are some settings which are not working.
> The mythbackend tried to access the field "channum +0" in the database table channel, which does not work.
