You can also download Rotel supplied pronto files from this site, and open with pronto edit or any of it's derivations. When you open up a button, you can view the hex for its ir command. Copy this hex and paste it into the RTI program in a user database. It works great, and once youve done it you can just open the file and drag the command instead of having to use the button repeat procedure - less time consuming in the long run.
