I am trying to get window Movie Maker to recognize my digital video camera ( A sony  DCR-TRV460). I currently have Windows 8.1. I have open Movie Maker and Selected import from Device. I then turn on the camera in playback mode and the connect the USB cable. I do not see my camera and then I hit refresh and still do not see it. I also tried it on my old computer running Vista and the same thing happened. I also tried it on my sister-in=laws computer and nothing.  I download a new Microsoft Essentials and checked the Sony site and they indicated the drivers were present. I do not know what else to do please help. Also after loading 8.1 my  Microsoft Lifecam HD-5000 camera is not working. In Skype the light goes on in the camera but the screen is blank with a circle going round and round please help.
