Thanks for asking.
If your receiver is supported, your remote will automatically appear 
in Remote Buddy as soon as you press a button on it for the first time.
You can find an up-to-date list of currently expressly unsupported 
receiver models on the "EyeTV Remote" subpage of the Remote Buddy 
website.
*Currently* this list includes the EyeTV 250, 250 Plus, 300/310, 
400/410, 500, 610 and EZ.
Support for additional models (including models from that list) is 
currently being worked on.
Best regards, 
Felix Schwarz
