I've a brand new Panasonic NV-GS500 camera - works beautifully, excellent video quality. I can transfer video to PC via the supplied software (Sweet Movie Life), but when I try doing the same thing via Nero, or Windows Movie maker, it triggers the playback via USB, appears to be recording the video, but the resulting file plays back at 90 mph. Is there a setting either on the camera or within the software which will sort this out?
