I have an iPhone 3GS hooked up to a pro hd sling box. I am unable to change channels on my iPhone while watching Yhe start up channel. In other words I can only see and hear the channel it fires up on and cannot change from there can anyone help??
What I understand from your post, is that you're unable to change from the iPhone.
First of all, what I would recommend, is to test the Virtual Remote from a computer, if you have the same problem, then check the following link:
I used to be able to control my TV with SlingPlayer or Watch on Slingbox.com. Now it doesn't work. What's wrong?
