Hi Michel,
my Card works since today and I have similar Problems with Scanning.
Can't scan some Transponders. In my fresh Channellist I can't find
ProSieben Germany, for example.

Will try a new Scan tomorrow during my Work, maybe its an temp. Problem.
With Windows I can access all Transponders on Astra 19.2E.

Bye and good Night, Elmar
