I'll elaborate on what John said. Rob has collected data on what setup codes are in all known upgradeable (by jp1) remotes from Universal Electronics (they make One For All and Radio Shack remotes). The data says that code 1377 (the one that DOES work for Direct TV) is not installed in any of the OFA or RS remotes that have been checked. This leaves you with three options:
One, you get a OFA remote that is phone upgradeable, call OFA on a weekday and have them upload the code for you.
Two, get a jp1 cable and build and load the upgrade into any jp1 compatable remote yourself.
Three, learn all of the commands you need/want to your universal learning remote. This may leave you with a few keys that don't fit, as the learning memory is small; and if you have any other keys learned from other devices it limits you even further.
