Hi David, slowly but surely the circle is closing :))))) Initially I wanted to know the frame numbers to navigate - guess what program ? :) - avidemux directly to the advertising parts of the video to cut that stuff out of my (visual) way :))) I didnt want to scroll through the video stuff to find advertsisings anymore... Sorry when asking...I did not understand your last posting completly...I am no native English speaker. What is the name of the programm to cut off advertisings? ATM??? IIRC??? And escape sequences...or? I think I am completly lost here.... HELP ! :)) Best regards mcc
