I agree, but what we should try to avoid is that similar code ends up in 
 three different places: the frontends, the generic dvb-frontend code 
and applications.

This duplication of effort doesn't really help anyone, in fact you end 
up with each layer implementing some magic retry mechanism and it taking 
many seconds to try same options over and over again. The error handling 
code for devices like hard disks and CD's has ended up like this.

One of the benefits of open source is that we can examine all the code 
to identify the best location to implement it once.
