I hooked up a Y RCA cable from my TV, and the 1 male jack is inserted to the DVD, white output. The other Y RCA cable i hooked it up on the Home theater system receiver, and inserted the male jack on the red output of the DVD. I wanted both sounds from the TV and home theater system. Sounds all great but i dunno if its suppose to be that way. But does this effect the right and left speaker of the TV?
