Hi
Now my card is successfully initialised but i noticed something.if i start vdr from terminal ,encrypted channels dont open.The same happens as i reboot the pc.Now if i shut down the pc and start again all channels open.Maybe it has something to do with vdr and one of the plugins? any hope to find a solution here?
