Not sure if you are asking about Multiplex switching or pre wired Cat 5 or HDMI wires? It would be nice if there was HDMI cables run to the basement and to the bedroom.
Multiplex switching is great when it works, hard to trouble shoot when it does not, and expensive when you have to replace the Multiplex/computer boards. Often times it's just a bad ground, but finding it can take hours by someone who knows what's he/she is doing.
Using LED lights with smaller wires and conventional switches would be the best IMHO.
