When I run InnerTube I get back a bad link from the Downloads code page:

The link is correct i can put it in my browser just fine, but the rawHtml has this in it:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "www.w3.org/.../loose.dtd">

... So it never finds swfArgs and my jsIndex is -1

private static string CreateTokenRequest(InnerTubeVideo video)

{

//YouTube variables

const string jsVariable = "swfArgs";

const string argName = "t";

//get raw html from YouTube video page

string rawHtml;

using (WebClient wc = new WebClient())

{

MessageBox.Show(" Link = " +video.Link.ToString());

rawHtml = wc.DownloadString(video.Link);

}

//extract the JavaScript name/value pairs

int jsIndex = rawHtml.IndexOf(jsVariable);

int startIndex = rawHtml.IndexOf("{", jsIndex);

int endIndex = rawHtml.IndexOf("}", startIndex);

string fullString = rawHtml.Substring(startIndex + 1, endIndex - startIndex - 1);
