Hey, I stumbled across this app today. It might work for us. I installed it and opened it and it didn't complain about not being able to find the IR, but I couldn't get it to work on my TV. Since my TV wasn't specifically listed, I just tried a couple generic LG settings since I know it uses LG codes. Maybe someone with a TV that's actually listed would have more luck?
