I'm a newbie here so hopefully I'll ask the right question.

I have been trying to find the RS232 codes to choose the channel on my LG 42LW6500 TV but without success. I have tried LGrs232 and have found that codes; ma are for the Tune Command, mb are for Channel add/delete, mc give channel up/down, but there does not seem to be a command to go to a specific channel. The TV has Freeview - the DTV option here in NZ and there are 14 or so channels to choose, we have three we use the most and I would like to be able to do directly to one of these via a button(s) - so a favourite(s). Don't really want to go down the Sky route.

Can anyone help with this?
