However, you can learn the database codes onto a 650 via an 800 or 850. I actually carry an old 800 in my laptop bag to use as a programming aid when I do 650s.
We install a lot of LG plasmas along with 650s. The LG remote does not have discreet power or input commands and the 650 does not have them in the on board code files. The code database in MX Editor have them. So I download the codeset into the 800, then learn the needed power and input discreets from the 800 to the 650.
Takes a couple of minutes to do and the client winds up with a more fool resistant remote.
I am a trained professional..... Do not attempt this stunt at home.
