I'm planning on buying a RF modulator to distribute video and associated audio throughout my home. I want a satellite receiver, standard broadcasts, DVD, and a security camera to each have a separate channel or channels (for the antenna). The RF modulator's that I've seen have composite video or S-video connections at best and standard audio inputs. From what I understand composite and s-video connections can't transfer a high definition signal. One modulator I found has MTS stereo sound (http://www.smarthome.com/7701RM.html). Does this mean that you ordinarily get mono sound through an RF modulator? Is there a better way to distribute audio and video signals without sacrificing quality?
