It sounds like you have what we call "the ghost band".  It comes and 
goes with minipreps, but we usually don't see it in lg. scale (2xCsCl) 
preps.  It's permanently denatured DNA and wont transform, cut or mess 
up your ligations.  Having said that, I still don't like it hanging 
around.  It's your call....best wishes.
