Orb vs Slingbox For TV Streaming With TP2

[deadwrong03]

i used the live chat on the site and the guy took my password and set it up for me perfectly now its working this is great i havent even set it up on my phone yet lol

but when i change my channels with the on screen remote it changes the channels on my tv at home as well. How can i get it to change the channel on the slingbox site, but not on my tv?

i have a cable box that broadcasts to 2 tvs one via a antenna that controlls a tv in another roomm that can watch different channels and one tv that its directly connected to...

on the back of my box i have a set of av ports for the tv thats in another room, the tv that the cable box is connected to and another set of av ports that say

what are these ports for? and can i use these to watch different programming and change channels without changing the channel on my tv ?
