Just adding my "me too" to this thread.

I am based in the UK with a RU950.

I have been using the X10 IR codes which are available from this site since time began.

The DIM and BRIGHT codes are not working since I upgraded to the latest firmware.

I have noticed a difference between the 3000 and 950 when using ProntoEdit insofar as the code database for a 3000 pcf has X10 available whereas the 950 doesn't.

Cheers

Dave.
