So I upgraded to the new 5LNB dish in anticipation of NESN HD and I'm a little disappointed with some of the Boston Local HD channels. Channel 4 seems to have some issues in the middle of the picture (looks like the pixels don't change fast enough between scenes- not horrible, but distracting enough), and channel 7 had no sound for a little awhile the other night. I figured with Boston being one of the first markets with HD Locals, issues like this would be resolved by now. Is anyone else in the Boston DMA having any trouble? My signal strength seems to be ok, so I don't think that's my problem.
