Yesterday I tried using sling from my android phone and it told me that all the tuners were busy to try again later. I'm not sure how that was possible due to the fact the receiver was not on and nothing was being recorded at that time. When it works it is a really nice feature but 80 percent of the time it has difficulty loading and then buffers frequently making it a pain in the butt to watch. I'm glad I only payed thirty dollars for the sling adaptor. I just wish it was reliable because I do like to check in on the ball games occasionally while shopping with the wife, if you know what I mean.
