Thanks for using our Answers Forum. I'll be more than happy to answer the questions that you have regarding the Slingbox. With the Slingbox, you have access to everything on your cable box that you would have access to if you were sitting right in front of your TV remote in hand.
Whichever cablebox you have the Slingbox connected to, the Slingbox controls. Meaning, the person at the house would have to watch what the person remotely is watching with the Slingbox. If you have more than one TV, I would connect the Slingbox to a cablebox that is not the main TV. I have mine connected to my cablebox in my bedroom since no one is in there during the day.
Hope this helps & feel free to contact us again with any further questions you may have.
