Has anyone out there had success getting the MX-1000 to learn codes for something along the lines of a Sony KPR-53CX35 53" TV? The remote SAYs it's learned all the codes successfully, but a bunch of the buttons don't work at all and some execute the learned function of another button. For instance the TV,Video1,Video2,Video3 input source buttons don't do anything.

Anyone had any luck?
