One more clarification: After "downloading" your .ncf file to the NEO you will ONLY need to re-learn the IR commands that you had to learn because they were not in the "built-in" database, you will not have to re-learn EVERY command. The degree of inconvenience of this depends on how many custom commands you learned in the first place. For my set-up (for NOW) it is about a dozen or so. The more custom commands the more hassle. For this reason, the utility of the NEO will reach a plateau unique to each user - in other words - you will program it to a point and stop, because each new device or change in the layout causes you to go back and re-learn custom commands. My NEO is sitting on the shelf waiting for Philips to fix the "freeze after jump" bug.
