Just wanted to say congratulations on your wedding.The setup i have personally is with an older box so it may be different with newer boxes these days but i have the coax cable go into a splitter and have one end of the splitter go to the tv and the other end go to the slingbox coax cable part, but the newer boxes are different so im not sure.
as for you sitting watching the eagles, if you have some sort of splitting device if your friend changes the channel on your sling box it will not affect you watching the physical tv in your home no but you would need to have a splitter for that. like i said dunno what types of connections the newer boxes have, i will be finding out shortly as im getting my own place with the fiance (wedding is sunday lol).
Sorry to the others for my off topic post.
