I need help installing Roku
I bought the Roku for Netflix, but installing it wasn't as easy as ordering it. I purchased an HDMI cable, but the two HDMI slots on the back of the TV are already taken by other cables. I unplugged one of them and the Roku started up but said that it didn't recogize the wireless router that the Roku is next to, then the message went away and I couldn't get it back to try again. That router is used for DirecTV On Demand.
Do I need a splitter or something for the HDMI ports? How do I get it connected to the wireless router?
Please walk me through this like I am a 1st grader, I am not TV saavy.
