Hello,

as more and more distributions are switching to udev, and udev automatically 
creates device like /dev/dvb0.frontend0 and also /dev/dvb0.video0, switching 
the applications to use these devices could simplify things alot.
I'm using a patched vdr which does this, and so I don't have to configure udev 
or use any scripts.
