So, I am finally getting my act together. I have installed my Slingbox 500 and expect to be able, using Apple TV, to watch Bronco games while on vacation in Florida from my Denver-located cable box. Now I find that I can only change channels by swiping up and down on my iPhone. I can enter a desired channel number on the "remote," and I can see the number come up in a box on the screen. Or, I can go to a station on the guide. But, there is no way to actually select that channel. Essentially, there is no "Enter" button after making the channel choice. Does anyone else think that this is an unacceptable situation? Does anyone know of a work around? I am using Comcast's Xfinity X1 On a Cisco box. Your thoughts will be appreciated.
