My provider is Time Warner cable and I jusy got a new cable box, an Arris HDMI converter/adapter? box. I am trying to set up my Slingbox 500 remote on screen and when I get to the "what is your cable box' section" they tell me that the ox is unsupported. Anything I can do? I can't find a phone number to speak to a slingbox tech person?
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.
