I think you have almost already solved it [1]. You may think of having a pin tag with a small cross (while the mouse hovers). If you see, people clicking the crosses often it's a good feedback that the tag may be wrong. It can help you correct these tags if not appropriate.
In addition, you should also think about adding tags for CAM RIP, BR RIP, DVD RIP etc. Movie torrent downloaders do care about such information.
