An interesting way is to record your own remote codes by a simple PC oscilloscope software and an IR receiver such as TSOP1738. Anything you record will be the original signal of your LG tv remote, so there will be no chance of error. Its simple & cheap, just requires an IR receiver & a diode.
When you read the waveforms in the PC, look for repeatations for each buttons. That's your code...
Then compile your own program....
