Unable to Determine Parse Mode and other related problems

One URL I test gives the "Unable to Determine Parse Mode!" warning as well
as the "Line 1
dator%2F1.3+http%3A%2F%2Fvalidator.w3.org%2Fservices> , Column 1: end of
document in prolog" while a nearly identical URL (HTML nearly identical)
succeeds without warnings or errors.

Valid URL: http://test1.calcxml.com/calculators/home-affordability?skn=504
Invalid URL: http://test1.calcxml.com/calculators/home-affordability?skn=502

I understand that the problem would have to be related somehow to the slight
difference in the two htmls, but I have no idea what to do to find out what
the problem is. There is not enough information in the warnings and errors
for me to figure this out.

1.	Why is it unable to determine the parse mode?
2.	Why does it think the html is empty?

If you browse to the invalid URL in a browser (except IE10 I believe, which
is why I am trying to figure this out), you will see that the invalid URL
does render and indeed returns html.
