I have universal remote that takes advanced codes for individual functions like ATT TV, Only a few UEI remotes have a roku setup code that takes advanced codes, they include the Inteset 422-3 remote, One-For-All urc-7880, and Insignia rmt-415. Anyways the advanced code for ATT tv is 00255, when I enter that into the UEI remote, my Ultra comes up with a screen to add the channel, when I click yes, theres a 4 digit code to enter it as a private channel. Each time that 4 digit code is different.
