I am completing my basement and will have a main DLP TV running HD through the cable box via component video/audio. Can I use the other coax or s-video outlets of the box to two other non HD tv's if I wish to view the same thing on all three? I may have to run through a RF modulator or a video switch first. Thanks for your help.
The keywording here is lacking in your question Eric... Is your intent to watch HD channels on the non-HD TV's? Yes you can use any output from your STB to connect to other TV's, but you have to factor in distances between the STB and the actual TV's you are connecting to. The best way is using coax as 7470 described, but depending on footages between points A B and C could give you other options or hinder PQ. If your intent is to watch HD channels, depending on which type of STB you have the answer is yes or no. If it's analog or digital channels only the answer is yes.
