Do the Akai 42" HDTV rear projection TVs or the Samsung 42" HDTV rear projection TVs have a fixed audio out for hooking up a home theater system? Can you turn the speakers completely off and run them through you home theater receiver and hook it up to a hdtv digital cable box? I have been thinking about getting an Akai 42" or Samsung 42" for our den but the guy at CC said you could not do what I asked above with the Akai. I am very curious about both.
