I am pretty new at installing satellites and had a problem come up. The customer has both E* and CATV. The E* is hooked up through coax from tuner as TV2. The TV only has one coax input. I currently have them hooked up to an AB switch, but they are not happy because when they switch from CATV the satellite is in black and white and they have to reboot the system each time. Any suggestions on a better way?
