Kinda hard to give any specific advice without knowing what you have and what you'd like to accomplish.
How many video inputs and what types of inputs on each TV set?
Can you run composite video, S-video, or component to the 2nd room?
Did you want to use a diplexer to bring in your FTA signal on the same cable as your TV antenna?
... and send it where?
I remember on my first system, I made up an elaborate wiring diagram to hook everything up.
Then, when I got everything going (in small steps), I totally abandoned my grand plan. -
Sometimes just adding a new DVD recorder can cause a major upset in how things all get wired.
It did for me last summer.
There's no ONE right way, but some might be easier than others.
I like to have plenty of A/V cables of all types on hand, just in case I get inspired. -
