there has been many posts about connecting different sources, here is a short breakdown on how 99% of these htib work...
you can NOT hook up devices such as a Wii to the unit itself because most do not have a hdmi/component in.
you CAN use it for audio one of 3 ways...
ARC via HDMI if your tv has ARC
SPDIF (optical typically) from the tv > unit
RCA Composite RED & Wht inputs - analog
the main benefit (imo) of having a unit with multi/extra ins is that you can run 1 cable to the tv and be done with it
most of these htib however you still need to hook everything up directly to the tv and then the unit gets the audio signal from the tv instead of the wii/ps3/bluray directly
