Update: I came home from work and the set-top box was displaying the time. I fired up the TV and voila! We have signal. All is right in the world.
Now, we have to bite the bullet and trade in our base-model box for the digital version so that we can use the HDMI cable I fished through the pipe for full 1080p HD signal.
After the 4th of July, I suspect.
Nice setup Bill! If you ever want to include a fine piece of hardware in that setup like a GoogleTV STB, just say the word.
