I've been checking out some really early VHS home videos. The 20'th Century Fox ones from Magnetic Video, Warner Bros, etc. Including titles that seemed to have dropped off the home video radar like "Visit To A Small Planet" and "The African Queen" These videos were released late 70's, early 80's. Most of them play fine, but some exhibit a slow picture roll. When fast forward picture search is engaged, the picture is in it's proper place. When it's in normal playback, the picture starts to creep upward, exposing the vertical blanking bar and the picture undernieth the moviement continues in normal playback. Is this a result of tape aging or some sort of early copy protection attempt. I bet those that have been into home video from the beggining might have an answer. Is there a way to fix it?
