Google's pretty much the only source left for me as well; I get most of my data from either the LIRC project (www.lirc.org) or the hifi-remotes website (www.hifi-remote.com), but when they run out, I can sometimes find config data hidden in other websites all over the place.

Almost all the devices using consumer infrared today send their data in a very similar manner -- usually, each time you press a button, the remote control sends out two numbers, a "device" value and a "command" value. (Most devices only use one "device" number; the only common devices I've seen with multiple device numbers are stereo component systems, where each component frequently gets its own number.)

Most consumer IR systems encode information by varying the duration of time that the LED is on or off. So, when someone reads the pulses off of their remote to construct a config file, they might either just list the length of each pulse received when a button was pressed, or (if they know the encoding method) they might actually figure out the original numeric values and write those down instead.

So, in short, what I'm looking for is a list that associates each button with either timing values or device/command numbers.

Search strings like "IR Protocol" or "Remote Codes" seem to work fairly well. Sometimes I can get a hit with "LIRC", as it seems many people generate their own personal LIRC config files.

(And, of course, if you've got a PC with an IR receiver, you can just run LIRC yourself and read off the pulses for each button on your remote. )
