Yeah, I tried that one as well. The MX-3000 also has an IR library for the 950. Some of the commands work, others don't. Volume half works. For now, I ended up just creating a 5 pulse macro for the volume so that every push gives me an increase or decrease of 5 steps at a time.
Just waiting on the MRF-500 and I will be done with it if I can get the 232 commands to work properly.
