It isn't necessarily a new keyset; it's just that there isn't enough support for the MT-Logic brand. The fact that the Wii can't recognize it probably means that the commercial universal remote industry doesn't support it very well; and, the fact that config files can't be found at the LIRC or hifi-remotes websites means that there probably aren't all that many MT-Logic customers out there. There is one more option -- you could reverse-engineer the original remote control yourself, if you're up for that kind of thing. I know that the LIRC server can do it fairly easily, if you've got a PC with an infrared receiver. (Most "media PCs" and most modern Macs have them these days.) This is, in fact, how most LIRC files are generated...
