1. So is the main difference between the Solo and the AV is that the Solo is if I want to watch HD programs on my device?

2. Obviously you need the unlimted data service through your phone but once you purchase the box there is NO other fee from slingbox?

3. If I was on the road watching something on my phone would someone at my house in front of that TV have to watch what I was watching or could they watch something else?
