I am thinking of getting my 3rd HDTV for bedroom. Have two hooked up to 622 already. One close by with component and fiber optic sound. Another 30 ft away by HDMI. Third one would be 60 feet away in another room. Realize that these would all have to look at same channel if they come out of the 622 but that is ok. Any way to do this without getting another HD BOX for the new TV?
