A:AnswerYes. You would need to connect the Slingbox to a family members home,friends, neighbors who have a working cable box.. This will allow you to stream their TV content.
A:AnswerYes it would, but the question is would the slingbox remote controller work with the converter box to change channels. This remote is designed to work with Cable TV boxes. So may not work easily with converter box.
A:Answeranybody can log on from anywhere with internet access. I dont think more then one person can be logged on at the same time but you can call sling media and ask them. I had an older sling pro and if someone was logged on you had to bump them off.
A:AnswerYou view SB on an Internet browser (like IE of Chrome). If your smart TV has a browser, then you can log into the sling website and watch it. Currently TVs may not do that very well.
