After 3 years using the MX-500 and reading the RC review I bought an MX-900.
One of its less endering qualities of the 500 was having to buy a One-for-all remote to enter 3-digit advance codes, then us it to teach the MX-500. I am now surprized to learn that, apparently, the MX-900 has this same "feature"!

Someone please tell me I'm wrong about this, but it looks like there are only 3 ways to get a 3-digit code into the MX-900. 1. accidently stumble across a function will work from one of the dozens of devices in the IR or universal browser and drag it onto the virtual remote, 2. find a file online that has the wanted code in it and is in a format that the MX editor can import, or 3. drag out my trusty OFA, enter the 3-digit code into it, and teach the MX-900. For someone who has already ferreted out the 3-digit code that works, none of these options is very appealing. Why doesn't URC all us to simply type in a known 3-digit code? Seems like a n0-braner to me.
