so i have a 2.1 creative speakers hooked up in my room to my airport express. i plan on getting the apple tv next month to hook up to my LG 32" HDTV. is there anyway to stream the video from my laptop to the apple tv and the audio to the airport express. im wondering because the speakers only have rca and not optical audio and i wanted the movies to use the speaker system instead of the tvs speakers. has anyone else tried this yet or know a way around it?
