In other words, if a lot of noise is injected into an old wire, will the signal go through the splitter and get onto the new wire and cause problems?
This really depends on two things: The strength of the noise, and the isolation between ports in the splitter.
The isolation between ports means how much signal is blocked between ports. Most splitters will have between 15 to 25db isolation.
This means that if the noise on the wire is 15db, it won't really affect the other ports, but if it were like 70db or so, it probably would.
This is also why if you hook up a splitter wrong, the TV looks like crap.
Most people won't have this problem.
Thanks to Mike G. for this question.
