interesting, i will take a look at this in the near future.
i also made a similar addition for 0.26 but due to the changes in 0.27 
it doesnt work any more and i havent had enough time to understand fully 
how it works now.

i have 2 dvb boxes i can test it with, both based on enigma2

also interesting for the problems i have.
but in my case i also need to figure out how to reset the ca module or 
similar via software so i dont need to physically unplug it and reinsert it.
not sure yet if a reset is enough, possibly i also need to tune to a 
channel.
