How can I view media from my computer to my ancient television?

I have about a 10 year old Sanyo television. I’d like to view videos and other media I have stored on my computer on it. I’ve already tried hooking up a VGA to S-video cable to it from my laptop with no success.

Now, I’ve been looking into these media web hosting sites like Orb. What is the best way to view the media on my TV. The only web-enabled gaming console I have is the Wii. So, I’d probably have to use it’s web browser to grab the videos I’d store through a web application. Which (free) website is best for this?
