How to access composite video in Optimum cable box.?

Question

I plugged my xbox 360 into the composite ports in my Optimum cable box. How do i access the video? I went through all the channels, but can't find it.

Answer 1

Are you sure that port is an input port?
If indeed it is input and not output, then look for somwthing like "Line 1" , it is definitely not a channel.
Check your manual.
