This page is not Valid ! - no results

I have been tying to validate one of the pages on my website against the 
XHTML transitional DTD. After getting past all the errors, I finally 
have the message:

This page is *not* Valid !

The validator then displays the message:

Below are the results of attempting to parse this document with an SGML 
parser.

The only problem is there are no results. The page I am trying to 
validate is 'http://www.mentalis.co.uk/dwid4/9/tv/2_test.htm'.

Thanks,

Nigel Ellis
