Hard to say if there are discrete inputs available. DVI's no use with your TV - no digital video input. I'm guessing that you're switching between internal cable tuner and the component video input on the TV, hence the need to scroll through inputs. I found a manual online, hoping to find if you could disable unused inputs, but that doesn't appear to be an option. Does the "Favorite Channel" option allow you to assign an input as a favorite? The manual doesn't indicate that it's possible, but if it could be done that'd be a slick way to jump to the component input. You could also use a VCR or cable box as your cable tuner, which would allow you to feed audio and video both to the 1070, so that the 1070's component monitor output carried all of your video for you.
