no picture on startup of ProgDVB

#1
Hello,

when I boot the computer and start ProdDVB I see no picture - the LED on the DVB-card also not starts blinking/lighting). Then I close ProgDVB, start the trial of DVBViewer and then I close DVBViewer and start ProgDVB again and then everything runs immediatly.

How can I fix this problem?
