I have a similar problem but not with sony s7000.
The pronto seem to learn the code to my cable music choice box but would absolutely not control any of its functions. I have tried copying to code to another remote and then to the pronto but no success. I also tried all of the suggestions given above including deleting and recreating template and no success. The pronto controls all my other gears except this piece. Any other suggestions are welcomed. Has any other person experienced this?
