After upgrading to RC3 I got some problems.
When trying to turn watch a tv channel I get the message "Unable to start timeshifting - Channel scrambled". This happens 95% of the times, sometimes it does work as intended. I got no clue why it works sometimes, no consistency. I have tried with local Mediaportal and a remote connecting to the TV server and the same results.
If I run FireDTV Viewer all channels work perfectly (and with faster channel switching). This means the card+driver works.

Found solution. Was me missing that the setup reset the CAM setting.
