Hi,

I'm an installer/programmer for an A/V company that I just started working for. I've been introduced to the URC MX-900 because this is something we sell.

Well, I HATE THIS THING! LOL

Really, I didn't start this to bash the thing. I would like to understand it a bit more to know how to use it effectively. Are there ways to make the programming easier? For example, today I needed a code set for an odd Sony TV. Some of the codes worked, but others did not. I wanted to use some codes from one set, plus others from another set, and I couldn't figure out how to do that. I wanted to learn the key functions off the factory remote too, and save that as another code set, but I couldn't do that in the 'custom' menu. Also, is it common for them to have screw-ups when learning buttons? I could go on and on...
