ok,i just got a Venturer theater system. i hooked it up last night here what i got a tv with 1 coaxial thing and the yellow, red, and white thing a comcast digital cable box with the 2 coaxials and the yellow, red and white thing i hooked up the speakers and i works fine when i'm watching a dvd but when i watch tv only the tv speakers work.
hook up the red and white thing (not the yellow thing) from the comcast box to the back of the theater system. Make a note of what port you connected it to (Aux1, Aux2, TV I'm not sure what you have in the back there) as long as the port is called in (or input).
When you watch TV use the remote for the Venturer and set it to the port that you connected the comcast box to. Turn the TV down and enjoy the audio through your HT box.
