3. Create a backup of the file Default Settings.mrs that is present in the folder C:\Users\Public\Public Documents\Noldus\MediaRecorder.
4. Open the file Current Settings.mrs from the same folder with Notepad.
5. Locate the line <PtzType>1</PtzType> and change 1 to 0. There is a line for each PTZ camera that you selected in MediaRecorder. Change the line for each PTZ camera. Important  When you selected the same camera multiple times in MediaRecorder, use the same method for pan and tilt in each camera. So for each camera, use either 1 or 0.

7. Delete the file Current Settings.mrs from the folder C:\Users\Public\Public Documents\Noldus\MediaRecorder.
