 Problem:  While in the EPG and watching on a DVB card you can only change
 the channel once (X key). Ivtv and bttv cards work correctly.

 Looking into this I found that CommitQueuedInput() was not being called on
 the second attempt due to set->Displaying() == 1 in the following code
 from tv_play.cpp (~1970)

 {{{
        // Commit input when the OSD fades away
         if (HasQueuedChannel() && GetOSD())
         {
             OSDSet *set = GetOSD()->GetSet("channel_number");
             if ((set && !set->Displaying()) || !set)
                 CommitQueuedInput();
         }
 }}}

 It seems in the DVB case there is something additional put up on the OSD
 (and never goes away). Maybe the signal monitor?

 I have attached a possible fix for this.
