I don't know that camcorder but you say it has the words DV-In appearing at intervals on the screen? It sounds like you changed some one of the settings as the camera is now expecting you to recording footage back onto tape in the camera rather than take footage from the camera and onto the computer, check the settings in the camera menu and see if you can change the DV-In to DV-Out, it must be contained in the instruction manual aswell.
