Greasemonkey Help

This is a YouTube script

Basically
in the URL, if there's the &hd=1, I want it to do this

if ($hd=1) {
        conf["width"] = 853;
        conf["height"] = 550;
}

Does anyone know how to do that?

I'm assuming this is PHP based, and if so one thing jumps out:

if ($hd=1) {

should be

if ($hd == 1) {

In PHP, like C, a single equals (=) means assignment; use double equals (==) for equality check.
PQ.
