If have a Dreamcast, you owe it to yourself and the system to get this cable for the S-video.  I don't have a VGA port on my main TV otherwise, I would have went that route.  It is a night and day difference over the composite picture quality though.  I was skeptical at first because other reviewers couldn't get the S-video to work.  It works fine for me with my philips 42 inch LCD TV.  The dreamcast is my favorite classic system and it will be getting more play time now since I can look at the graphics and not be disgusted.  Sword of the Berserk, Sonic Adventure, Gauntlet Legends, etc. all look great.  The cables aren't as solid as the ones that came with the system but, they are of decent quality.  Buy these now!
