    I have an early 2009 unibody 17-inch MBP and a new 2010 LG 50" LED HDTV (model PJ350). I got a mini displayport adaptor that allows me to connect the MBP to the TV using an HDMI cable. The video display is great but there is no sound, and I am aware only the new 2010 allow sound to go through to the TV and not my 2009 MBP. So I connected an AV cable through my MBP headphone port to the AV connection on the TV, but I get sound only on the AV menu. So if I select the HDMI mode I can only see video with no sound, or if I go to the AV mode I only get sound and no video. Is there any way I can see the video through HDMI while getting sound that is coming through the AV at the same time? I can't figure out how to get it work simultaneously. Thanks!

    Ok so I got it to work now with an audio in RGB cable, but my itunes music videos keep popping up and playing. How do I disable itunes from popping up and playing when the RGB audio cable is plugged in?
