A:AnswerSling tv and Slingbox are not the same. A Slingbox mirrors what would appear on your home tv, whether it is from cable or plain old rabbit ears antenna. It allows you to see remotely what is happening on your living room tv. It does NOT provide content, it only allows you to watch what is on your home tv when you are away from the house. If you have cable at home, you will see the same thing away. If you do not have any tv reception at home, the Slingbox will not provide content that doesn't exist already.
A:AnswerWith the Slingbox, you will be viewing the content from the Uverse equipment (i.e. DVR) in your home. However, with the Uverse app, you are viewing the content streaming from the Uverse servers not your DVR.
A:AnswerYou should be able to use any Internet connection you have already established on a device, so no, there is no further need to use vpn. As you have probably noticed, though, vpn makes everything slower.
A:AnswerIt should. The box connects to your NY cable box- the only caveat here is that your son will be controlling the NY cable box- he will be accessing what is being played on it- and can control it. It is a perfect set up if you can connect the Slingbox to an optimum box that is not watched when he is away. If it's attached to your ONLY cable box then he will see only what you are playing- OR he will be changing the channels you see on your TV.
A:Answerif you are watching the same station as she wants to watch, then yes she can. if she or you change the channel to something else, you both get whatever station it was changed to. basically, you are remoting into your PA cable box and she can make changes to it while you are right there watching it!
A:AnswerMy experience has been that only one person can view a stream at any given time. If another person comes to watch the app will ask if you want to boot the other person's active stream.
A:AnswerThe Slingbox itself will not, but if the source you are hooking it too can receive them and the Slingbox can control it that source, you can view them.I have my Directv DVR hooked to my Slingbox. I can see everything on my DVR remotely using the Slingbox.
