I have the problem that after standby/hibernate, the TVServer cannot descramble channels anymore. This occurs every other resume.

However, with todays SVN, when changing to a scrambled channel after resume, MP was unresponsive afterwards. I had to kill MediaPortal.exe with the taskmanager! This occured once. In the other cases, MP shows "Channel is scrambled". After restarting the TVServer, the scrambled channels do work.

Please find attached the logs.

Best regards,

Andreas
