I have a Slingbox M2. We recently changed the Comcast cable box that the Slingbox is controlling to a different model. How do I change my Slingbox to match the model number on my cable box? Currently, the remote control function on my Slingbox devices does not match the new cable box. The new cable box model number is PA PR150BNM, which has the A/V cable inputs. Any support anyone can provide would be greatly appreciated!
I see that you recently switched cable box, you would need to reconfigure your new cable box.
Bellow are some useful links;
