Just did a Regza 40" LCD with URC codes out of their database. Rock solid. What control system are you using? URC or RTI should have standard codes in their databases. I used TV/Video + (#) to get to the proper inputs. As far as I am concerned, that is as reliable as a discrete input.
There is no truth anymore. Only assertions. The internet world has no interest in truth, only vindication for preconceived assumptions.
