You don't need a 6131, and they are very obsolete at this point. Most cable remotes made by UEI will work using Video 0081 (20081 for remotes using 5 digit setup codes). For example, the $6 Comcast 3DVR
remote will operate most functions out of the box, and we can tell you how to customize other buttons to do the rest of the functions. Or, if you have or prefer another remote made by UEI, tell us the model and we'll probably be able to tell you if it is programmable.
