My guess is that the programs are asking where RDF files are stored, and where image files are stored. All of the programs will start without a RM file, and IR has no use at all for one. Make sure to follow the instructions 3 and 4
I'd start with this rmdu file
. Customize it using the Sony page
to add additional functions. Use the BD function as an example-- you can see it on the Sony page--16.40, command 22. Look on line 50 of the RMDU file, and notice the 16, 40, 22(in the OBC column). You can add HDMI inputs in the same way.
