It's odd that a learning remote has any significant problems with device compatibility - the only devices that should be a problem are those with abnormal IR frequencies, RF-only devices, or something like the PS3 that uses bluetooth for the remote (although I've heard that there's a USB dongle coming that will allow IR remote control of some sort for the PS3). I can certainly see where the database would be incomplete (companies like Outlaw and OPPO might not be included, and newer devices like the Xbox360 would also be unlikely to show up), but learning capability should make that a somewhat moot point.
