How can I watch HD video files stored on my computer on my TV?
The ONLY way to get a TRUE High Definition picture is to connect your computer to your tv using COMPONENT CABLES or HDMI Cables. You can NOT get an HD pic using RCA cables (red, white, yellow). You can NOT get an HD pic using S-Video either. You MUST use Component or HDMI/DVI. Sure, you WILL get a picture using S-video/rca BUT you will NOT get the picture in High Definition. It will be substantially down-converted by the cables used.
