i think you need something to convert it or just buy a cheap vid card w/ s-video heres a link for a cheap card to do that cheap s-video card
If you're thinking along the lines of for HDTV, I am pretty sure you can get breakout cables that take vga directly to HDTV component video. Going the other way, from component to VGA, is much more expensive ($60 converter box)
At one point I think I did find a VGA to s-video cable but lit was after searching for a while and it was like 20 bucks for the converter.
well wut about this cable http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=3759&item=5148414602&rd=1 It says " Please, check your PC & Video Card manual or manufacturer to make sure that your VGA card has TV-Out function capability to ensure this cable will work for you!" but if u look at the pic there is a vga connection and it goes to a rca video output or s-video. Doesn't make sense
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=41999&item=6728951197&rd=1 well here is a better pic. Look at the inputs and outputs. The outputs r for s-video and rca but the input is vga. Yet it claims Please, check your PC & Video Card manual or manufacturer to make sure that your VGA card has TV-Out function capability to ensure this cable will work for you! strange
