Stupid companies. My GMX account is not even freemail, I'm paying for it...

Maybe they don't have anything to say about it, because it only exists in

No, the TT Windows driver seems to have a register dump function (which I
don't know how to activate) and contains a list of strings will all

DVB-S2 function is actually somewhat unfinished and requires host CPU
interaction to work. Maybe we should wait for a fully finished
