Gonk, thanks for your quick advice. I check the link you sent me on that compnent video switcher, but it said to be for video switching. I assume the back of that swither must have 2 sets of component outports and 1 set of component inport. In this case, we can only switch 3 cables' sound signal (say front right, center and left). Then how to swith the other channels (back right/left and the woofer)?
Need to buy 2 component switcher?
Any idea?
Kwok
