I am trying to program my Flirc to work with my comcast remote. It will let me sucessfully program one button, but when I go on to the next one and I get button already exists. After I stop it and see what buttons it took, all the buttons light up with the up button. meaning: I press "1", "up" lights up.... I press "ok", " u"p lights up.... I press "down, "up" lights up. If I use any other remote to program it, it will work fine. Is there a know issue with Comcast remotes? I even went as far as to unlock the remote and try programming it with the tv function on the remote. that worked .
