Just got a new Sony 720 VCR. However, it seems to be quite loud. We previously had a cheapo Goodmans thing that was, to all intents and purposes, silent. The Sony whirrs (for want of a better description) while it plays. If there's a quiet bit on the tape or on what we're taping, you can hear it. Is this normal for a moden video (either Sony or other brand)? It doesn't drown out the sound, but you can hear it in the background... All help appreciated!
