i bought the apple dvi to video adapter yesterday for $15 and I also went to Best Buy and bought the S-video cable along with audio cables. i thought I hooked everything up okay because the video projection is working just fine. on my tv i can see what my laptop projects, but I am doing something wrong with the sound. when i hook the sound cord into the t.v. i just get what sounds like when your tv is on a blank station with the volume at full blast. do i just need the s-video cable and a sound cord and that's all or do i need other hookups? i know this might sound stupid, but i figure I would ask the experts instead of messing around with it forever. by the way, i have a Samsung LCD-HD tv model LN-R269. thanks...
