Same Stations list 3 Times in Guide

I noticed I have NESN (New England Sports Network) HD on 5434 and also HD 434 and Digital 434 . Why is that????? Is one prefered over the other? I'm on the Eastern Arc.

HD channel only has select programing on it. Most times have nothing so you need the sd channel at 434. The HD channel at 434 is from 5434 and is mirrored at the sd channel location to make it easier to find.
