ok so if i got some thing like this http://www.amazon.com/Monoprice-4-port-Component-Switch-Learning/dp/B001TK9SEE/ref=sr_1_2?ie=UTF8&qid=1361866421&sr=8-2&keywords=component+switchbox
and the vga to component adapter, in a nut shell i would go from the projector to the switch with the red/blue/green component cable to the vid out on the a/v switch, then plug my cable box vid out to vid in #1 on the a/v switch, i'll get my cable tv displayed on the projector, and so on for #2 and number #3...
think got that right,
whats really confusing me is what i need to do with the soundbar http://www.walmart.com/ip/Sceptre-SB20202B-Slim-SoundBar-with-Audio-Fading-LED-Technology-and-3D-Surround-Sound/22226861
is what i might go with,
it has the red/white outputs the red/white would go to the out on the a/v switch, and i would be good to go? so which ever switch i had it on would both be getting audio and vid right?
