These codes don't have anything to do with RAV2000 or any other specific remote. They'll work for anything if you have a way to get them in there. And for Prontos and URC remotes it's easy.
Here's one thread where I mention how to use Makehex:
[Link: remotecentral.com]John Fine has also posted instructions numerous times. A search should bring up some examples.
After using makehex you'll be left with a plain text file containing all the commands as Pronto Hex. You have to then use IRPanels or ProntoEdit to make a CCF with the commands you want (the ones mentioned in the Yamaha PDF).
When you edit the IRP file to drop onto Makehex you have to specify the device number (and subdevice) in Decimal. It's 209. Funnuly enough, the same devce number as a Yamaha projector discussed in this thread:
[Link: remotecentral.com]Hopefully these threads and the makehex readme (please make sure to read it) are enough for you to get this all going.
