Here's the complete set of IR codes for the 575.  These need to be converted to Pronto Hex.  Take the IR code listed in the Yamaha PDF files, and substitute a space for the hyphen, and enter that into the Yamaha Pront Hex converter.

For example HDMI1 (main zone) is shown as 7A-4738.  Enter 7A 4738 into the converter.  If you don't include the space or put it in the wrong position, the converted Pronto Hex will be incorrect.
