Tvheadend

Hi all,

I am running an oscam server on a dreambox and it serves the other dreamboxes without a hitch. I have now installed xbmc and tvheadend on a pc with a tt premium card and have been able to watch unscrambled services without a problem. However, if I go to a scrambled service (paid subcription) xmbc complains in the GUI "no input found". Needless to say, I have got black screen.
The tvheadend connects to oscam server:

xbmc gives the following messages:

If I understand correctly, I do not have to have oscam or CCcam running on one pc with thvheadend. tvheadend descrambles when provided with encryption keywords, correct?
Any help is greately appreciated, I am tearing my hair out with this.

Thank you so much for this great software!
