Hello, I have a new flat screen TV with the red, yellow, white connectors (one set) on the back of the set. I have a DVD and a Roku. It's a hassle turning the TV around, unhooking, hooking up the other device, etc. Also, the headphone jack is in the back (on the side - difficult to reach). Are there external ports, jacks (whatever they are called) so that I could a. plug everything in or b. have easier access to just one set of connectors. Thanks.
