I have a brighthouse system that I am connecting my slingbox pro to. The only thing that I have a problem with is the remote controle. I have used all the different types of remotes that goes with this system and none of them work. I called tech support and they have no answers to the problem. I was told that we need a custom remote made.
I assume you have already done a proper Forum Search for your model number in case other people have already answered your question ?
If so and that didn't help then check out this thread: https://community.sling.com/thread/3300?tstart=0
Come back if it that doesn't help either.
