You have to get the contents of www.yahoo.com, not just pass in the name. Try this:

$html = file_get_contents("http://www.yahoo.com");
$dompdf = new DOMPDF();
$dompdf->load_html($html);
$dompdf->render();
$dompdf->stream("sample.pdf");

Good luck with DOMPDF. It's actually pretty good for what it does, but the last time I used it a year or two ago it had trouble with anything even remotely advanced (like nested tables).

Using DOMPDF on the yahoo home page will probably give you some really weird results.
