Hi i am in the process of buying a telly (actually i have ordered it) anyway i have just realise i think it has no headphone socket however, it does, as well as it saying built in speakers, have and i quote.... Line out.... left/right and sub. will this be a seperate audio out and not interfere with the built in speakers?? and if not, will i be able to hook this output up to some headphones (am guessing just the l and r will do!!) if not i better cancel my order before it arrives!!!! cheers M.
