I am a new comer to sling box. I am living and working in the Dominican Republic. Several friends have slingboxes and they work fine here. I have read several post regarding screen freeze and that is my problem here. I am using an Ipad 2 with slingplayer installed. When I connect, it opens fine with audio and video. After a few seconds the video freezes. It will freeze and unfreeze several times until it ultimately looses video and audio all together. While home for the holidays, I reset my slingbox and checked for upgrades. At home, Birmingham, Al, everything worked good. I watched an entire football game on it and it never missed a beat.
