Just did a test. I programmed my regular VCR button for the 0618 code. I push the up arrow button and my Panasonic VCR starts to play. So It is not taking the 0618 code at all. I'm not getting any error message. I also tried some off the wall TV code to a brand I don't have and programmed the TV button. It still controls the TV. So I went to extremes and did the "clear all" command. I watched the remote display and it confirmed. The remote is still programmed, and it did not clear. What gives.
