I had the same experience as allamand. Some OEM remotes worked better when pressed prior to the learned NEO button, some just the opposite and some did not matter. Also, I found distance from one remote to another was both critical and remote dependant. Once I got one button to work, I kept the distance the same nd learned the rest. Some were quite fatsre than others even on the same remote.

Anyone know how to learn a "short blast" IR signal, such as the input selector on the Kenwood VR-309?
