I have recently purchased a new phillips freevents LS1600 pc and have been trying to work with windows movie maker. I have a digital camera and have been trying to "Capture From Video Device." However as soon as I click this option it tells me " THIS DEVICE IS CURRENTLY IN USE. CLOSE ANY OTHER APPLICATION THAT IS USING THIS DEVICE AND TRY AGAIN." I do not have the foggiest what else might be using it or how to close it down. I am probably missing the obvious but hhhhhhhhhelp. Thanks.
