I've concluded that my HD signal is much worse through my D* HR10-250 than directly to my hp 5880n HD DLP set. I'm using a CM 4221 antenna with a RS amp then to a two splitter. After that one line goest to my HR10 and the other directly to my TV. Watching the same channel on the Tivo is impossible b/c of signal loss versus' the same channel on the antenna input on the TV. Is this possible? What could I do to fix the Tivo side?
