I just bought a 2nd TIVO. I wanted to put the old one on my Sony rear projection TV downstairs. (hard drive is noisy and wanted the quieter new one in my bed room) The video from the TIVO on the Sony TV is all messed up. Alternating bands of red, yellow, blue. This TIVO works fine with a 20"JVC. New TIVO works fine on Sony. Tried both RCA plugs and coax output with same result. Any ideas?
