I'm trying to program my Comcast On-Demand 3-in-1 Universal Remote to "learn" my LG DVD / Home Theater system, but the manuals provided don't offer any codes for LG devices (besides TVs). Does anyone have any idea where I might be able to find it/them? I tried (as the manual suggested) the method involving alternating between the AUX and POWER buttons (preceded by holding AUX, and then 9-9-1 once the button blinks twice, for those of you who are trying to figure out what I'm talking about). I did this for quite a while and the remote wasn't able to figure out how to turn off the system.
