[mythtv] [patch for testing] DVB No Signal

[Anders Hanson]

Hi!

I think I have found the problem that I have had with my Viaccess CAM.

The problem is that quite often when changing  channel the CAM is 
looping in a "no rights" menu!

I have tested with both "On demand DVB" enabled and disabled.
What I've noticed when running with it enabled is that the DVBCam object 
stored in the DVBChannel is never deleted
but everythime the dvb is opended a new DVBCam is created (at 
dvbchannel.cpp:151)

I think that the CAM has to be paused/stopped when changing channel, 
because I get the 'no right' menu
just after the 'DVB#0 Successfully tuned to channel X.' but before the 
'Videostream: ...' and 'Audiostream: ...'  logs.
