I have a new HD LCD TV (2 tuners), a HD cable box, a TIVO and a Recordable DVD player. I've connected the cable box directly to the TV with Component cables. I've connected the DVD player directly to the TV via composite/RCA cables. I've I've attempted to connect the TIVO, using coax, as follows: from the wall to the cable box, cable box to TIVO, TIVO to DVD, and then DVD to TV. My cable signal is great, my DVD signal is great...but the TIVO is a problem. I have the TIVO picture but no sound whatsoever. I can't figure it out what's going on at all. I need one of two things: advice from someone here, or advice on how to find someone or some company that can come in and help me figure this out.
