Movie Studio Platinum does not recognize my Sony HDV camera. I go to capture video, tell it to look for an Mpeg 2 device, but it errors "no device detected". I've got Sony's capture program listed on the 'video' options menu under preferences, and selected "HDV device"n at the outset, but it won't recognize the camera no matter what I do. If I switch the camera to DV, it will recognize and capture footage, but not in HDV mode. What's up???
