I would check the level of the table and VTF like others have said. I have a SME IV.Vi and set the anti-skate to 1/2 of the tracking force of 1.7, so mine is set to about .85 or even less, my scale goes from zero to three. I set the needle down quite close to the starting track to avoid any skipping but I'd say this is a common practice on all TT's. I have no tracking problems and it sounds great.
Good luck,
Mike
