I have tried to capture video using Windows MovieMaker2, ImageMaker, and WinDV through the FireWire port. All show the same issues. Cam is recognized and controllable by the progams but video capture fails -- no video is shown on preview screen and it remains blank despite showing on the LCD on the cam (JVC GR-D72u). All hardware, cables and ports work fine with other peripherals. I've searched the web and others seem to have this problem using Windows XP, FireWire port, and late model JVC miniDV cams. JVC is as helpful as ever, as is Microsoft. Could there be a driver incompatibility with these JVC cams? Any updated FireWire drivers that may work?
