How are you performing the validation?
Many of the validation errors you are reporting are for a strict doctype.
the page is using the 4.0.1 loose doctype though.
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">
if you try validating this using a different doctype, it will fail.
