Don't get FIOS, first the TV guide. They have all the pay service that you must get past just to view your listing. They have a "subscribed channels" that goes back to their default setting.
As for the installation, I was at work and had the wife call when they arrived. I spoke to the installer about what was need to be done to avoid any problems with security CCTV. He did the job the easiest way for him.
If your conversation with the installer was anything like your post I can see why he didn't understand what you were saying.
