[mythtv] DVB Development

[Anders Hanson]

Is there any plan on forwarding the CAM menu to the frontend soo that 
the user can interactivly choose
what to do if  a 'no right' menu is displayed.  The most annoying thing 
with mythtv right now is that sometimes
I get a 'no right' menu from the CAM that is repeatingly showing up 
until another channel is tuned (actually the last
channel that worked).

If anyone can guide me to the rigth lines of code to implement this then 
I can try to make a patch that adds this if
no one else is working on this already.
