Hi to all
Pleace read this answer from the philips support care center (and thanks to them for the fast and quick support, great!):
Recently you have asked us about problems using the learned codes on your Pronto remote control.
Assuming you have the RU950, we can confirm this is a problem in the latest version of the firmware. We are working to resolve this issue, but meanwhile you can use previous versions of the firmware, available from the files section of
www.remotecentral.com. We are sorry about the problems caused.
We hope we answered your question satisfactorily.
