Advertisements A while back I bought a Slingbox 500. Since it has several inputs, when I first put it in service, I configured it as follows: SOURCE Composite: Unconfigured Component: AT&T DirecTV Now Streaming Player HDMI: TiVo Mini I recall that when I first put it in service, was slightly surprised that their wasn't some sort of HDCP issue when I ran the HDMI cables from the TiVo Mini to the Slingbox 500, but all worked well. More recently, however, I have been getting the message "HDMI connection not permitted. Press SELECT for more information." Is there, or was there, some sort of firmware change that is causing this?
