On the interface from iPad SlingPlayer app to Roku I noticed on the first time I had to enter the IP address of the Roku. That Roku was wireless. Then I added a second Roku in another room connected via ethernet. The app found it w/o having to enter IP address but I'm noticing now that it changes which one it considers Roku 1 vs Roku 2. It doesn't show either's IP address so it's kind of a guess when I try to transfer which one I'm using.
