There are not discrete codes for the surround modes that I am aware of. There are, however,
several Pronto ccf file libraries available for the 950. If you have a computer cable for your Pronto Pro (not sure if it's standard or not), you can skip the learning process entirely.
As for learning commands to the Sony, I used my RM-AV2100 with a 1050 (never have set it up with the 950). For what it's worth, the only troubles I had with the 2100 were related to the way it learned commands that were signal length sensitive (the "up" and "down" commands for setting up my VCR, for example) -- nothing that related to the 1050's remote.
