Sorry for the ignorance, but I need an adapter from two RCA audio jack to the 3.5 jack. However, looking back on my projector I see three RCA ports. Is the third one for video?
thanks

If this is what you have, then the yellow jacket RCA is video, the red is audio right channel, while the white is audio left channel.
