I've just got a new LG LCD and the manual contains a list of r/c button codes plus some discrete codes (can't believe this happens very often!). So I have used my pronto to learn one of the codes from the original remote and used DecodeCCF to look at its details. Having found that the code matches the one listed in the manual I thought it would be fairly straight forward to generate a new one for one of the discrete codes; maybe it is but I can't work out how :-(
