I'd start out trying the following codes: 007, 206, 207, and 080. I'd also try 014 (the code from the 950 manual, which you've probably already tried). On the other hand, I've gotten to the point recently where I don't even use remote codes when I have a learning universal remote and the device's original remote to learn from - it doesn't take very long, and it lets me put the commands exactly where I expect them to be.
