O.K. What I understand up to here is this:
You need a Technisat Conax card:
In which you need to buy charged 1, 3, 6 or 12 month MTV Unlimited card:
Now, the Technisat Conax card is yours, in which works with any Conax embedded receiver or a Conax compatible CAM. The MTV Unlimited card comes with a number that is shown only after you scratch it on the card. That number is to charge the Technisat card with the months you have purchased and will start counting when you activate it.
What I can't understand yet or haven't found out is that you have to introduce the number at the mtv-unlimited.de site. But how do you pair the number of the Technisat Conax card with the number that comes with the MTV Unlimited charge card?
UPDATE:
Is this the web page that you can charge your Technisat card with the MTV Unlimited ticket?
