Youtube view - how does it work?

Hey, I've been working on a script and there's something I don't get, how does youtube count the views? I create a tool in C that views a youtube video, and refreshes the page every 15 seconds, I left it running and checked back 24 hours later and noticed there's no change in the views. the tool uses IE to go the youtube page.

so, what's the secret? how does youtube count the views exactly?

BTW, great forum.

i think its cookie / ip ... just a suggestion but i view one of mine and the count DOES go up but i watch the whole movie
try setting it to refresh like 20 seconds after the movie finishs?

I tried using longer delays but I'm still getting the same results, i mean it's 200 views for every IP right? doesn't seem to be working. maybe it's a problem with IE?
