The Slingbox can be hooked up with this cable box in one of two ways:
1) Use the composite (red, white, yellow) ports and cables to hook the Slingbox and cable box together (this will give you a standard definition signal).
2) If you wish to get an HD signal to the Slingbox, we recommend the use of an HDMI adapter, which will allow you to hook the Slingbox up to the cable box using the HDMI port in your cable box, and the component (red, blue, green, red, white) ports in your Slingbox.. Here is some information on this:
Hope this helps!
