The Phillips 9200,9400,9600,9800 remotes can learn the commands from the U-verse remote,not the box itself. The Phillips remote must be connected to a computer with the software running. If you want to test it, have the U-verse box there and a 9200 remote.
You don't need the original remote.But you will need the U-verse codes.I think that device came out after Phillips created their database. Lots of codes can be found here, but that one is not listed.
[Link: files.remotecentral.com]Perhaps someone could upload their own codes to the Remote Central database.
