The Live value can only do four-channel EAX, as far as I know. You should be taking the front channel analog out on the back of your card to some sort of amp for your 2 front speakers, and ditto for the rear for 3d gaming (hopefully, you have either two amps, a reciever with four separate RCA inputs, or a set of four-channel computer speakers that can take the output). I think you can pass thru digital via the SPDIF for DVD movies, as long as you have a digital decoder that can decode the signal for you. You can't (as far as I know) split EAX up from the SPDIF out via a digital reciever and get 3d sound for games, but reverb effects and such can of course be heard with a 2-channel setup... Live also won't do advanced HD (audigy only), but 4-channel EAX is worth the effort.
