So I now have my beautiful new mini with plex, 5.1, a 46 inch sony and a harmony 1. I'm thinking the next move is a Slingbox. I travel a lot and would love to access my tv on my macbook and iphone (when the 3G streaming app comes out). I don't really understand that well how it actually works though. So a couple of questions .... First off, when the Slingbox is accessed via an external source like a macbook, does it basically control my comcast dvr and change channels on it so that if someone else is watching at home, the station will just change on them or is it independent of whatever station the dvr cable box is on? Secondly, which one should I be looking at, the Solo or Pro? I do have lots of HD stations available with my cable company, but I'm guessing that HD will only really work at home via wifi or if I have a good internet connection in a hotel .... which is sketchy at best. And HD won't apply when used with the iphone, correct??
