i'm installing 3 DirecTV HD (non-DVR) recievers at a restaurant and want to be able control them with a touch screen keypad. my problem is i need the 3 recievers to all be on separate ir banks so when the keypad sends out the signals it doesn't change all 3 at the same time. i went throgh the program remote setup and thought i put one on DirecTV, one and AV1 and the other on AV2 but it's not working quite right. Any ideas?
