Comment:

 (In [25642]) Fix issues with DiSEqC caused by [25543].

 Creating the LiveTVRingBuffer before the channel change operation means
 that
 the channelbase::sourceid may not be up to date when multiple sourceids
 are
 associated with a single input.  Therefore a call to CheckChannel is
 needed
 to determine that information.

 Also, when initializing the inputs in ChannelBase, retrieve the "default
 input" from the DB in case the capture device is opened "on demand".

 Both of these issues could result in incorrect program information being
 displayed when changing from one channel to another in LiveTV, as well as
 tuning failures due to DB lookup problems.

 Thanks to Gus Bourg for discovering and diagnosing the problem with
 DiSEqC.

 Thanks to Benny Sjöstrand for discovering the issue with opening devices
 "on
 demand", and fixing it.

 Thanks to Mark Buechler for his help in analyzing log files, and
 diagnosing
 the problems.

 Fixes #8742
 Fixes #6719
