Even more info:
Then UR19A remote sends RF not IR codes - that's why the Neo can't learn from it. The PUR08 looks like it will work with the Neo - I think this one does the IR comands to work with the IR543. - I'll email 'em and find out for sure though.
The PURO8 is a Universal Learning Remote with X-10 control of lights and appliances. Features backlit keys and a standard code library in addition to the capability to learn new IR codes from other remotes. Mode buttons include TV, VCR, CBL, CD, AUX1, AUX2, SAT and X-10
