<meta name="generator" content=Adobe GoLive 5">

Can someone explain what the information in the above meta code means?

I need to build a website similar to the one where I copied this from and I wondered if this code would be relevant to what I need to do. When I typed it into www.google.com, I ended up at this website. I hope someone can help.

You don't need it in your site. You'll want your meta tags to be appropriate for your own content. You'll also not want to use the keywords and description in the head tags of the site you copied the code from.

I want to put a video in my webpage so I am questioning what the "Adobe GoLive 5" does. Would I need that for a Flash video?

The generator tag defines the name of the program which created the web document. Adobe GoLive 5 must be a web design program that the webmaster used to create that page. META does not affect how your site will act or appear.
