hooking screen on vhs

[drh4683]

I am not certian of the problem here, as it seems to be common with all the tube type tvs. Anytime you watch a video through the vcr you get a pulling/hooking picture at the top of the screen. It can be corrected slightly by the h hold and tracking but can never get it to go away even when changing vcrs, so I assume it is something to do with the design of the tv. Anyone know why this happens and how to better correct it?
