A:Answer Based on the description, this issue most resembles what happens when the cables used on the camcorder are mismatched. Please make sure you are using the original A/V cable for the camcorder or the same type that it originally came with. Substituting an A/V stereo cable in for an A/V mono connection may cause the video and audio channels to bleed into one another, creating static/buzzing in audio and issues with the video. S-Video only supports video, so an appropriate audio connection will still need to be made from the camcorder to the capture device.
