[mythtv] adding a working fallback if DefaultTVChannel is not found?

[Petr Stehlik]

Hi all,

would it make sense to add a safe fallback to first (or any) channel of
given sourceid if the DefaultTVChannel for that sourceid was not found
(for any reason)? Perhaps using something similar to the following SQL:

SELECT channum FROM channel WHERE sourceid=<SID> AND visible=1 LIMIT 0,1

I could watch DVB-S again without getting the error below (I know I can
hack the DefaultTVChannel in DB directly but if the fallback was there I
wouldn't have to).

                        Most likely, your DefaultTVChannel setting is wrong.

Thanks for considering.
