I'm not an expert by any stretch (I got my first pronto a few months ago) but in my limited experience the best thing to do is get the ir codes directly from the manufactuer's web site and enter them directly into your MyData base. Learned codes are full of extraneous stuff and the Philips database is not that easy to use (eg generic devices and you can't tell which codes are in the device until you open it up) and the codes don't always work. I was surprised at how many companies put those ir codes on their web site although it is not always easy to find them.
