Is this remote for controlling computer equip or will it control a tv, cable box, receiver, and dvd player? I have a universal for controlling all my home audio/video stuff, but when scrolling through the cable guide, I have to wait 2 seconds each time I press the channel up/down button in order to press it again. I'm impatient and looking for something that will move the guide quickly just like the original cable box remote does. Let me know.
