I recently moved to Oregon and now receive the Eugene local stations. I have noticed on all of them pixelation that is consistent and terrible. This does NOT happen on any of the 'cable' channels. When I got the Sacramento Ca. locals at my old house I had no problems whatsoever. I checked my signal strength and all three tuners are in the low 90's. My Tivo is (I think a R10 SD). Any ideas why the locals are so bad?
