Hey, I have tried playing movie files from my laptop (mainly AVI and MPEG)on to my TV using S-Video. The picture comes up fine....but the sound does not match the peoples lip movements on screen. It seems to be a few seconds delayed. Sound hookup I am using is 2 RCA plugs (white and red) into my amp, and then into my laptop headphone port. Can anyone please help me and tell me how to get the sound matching the picture?? Thanks a lot.
