Problems with some doctypes?

I have installed the w3 validator on my site which can be found at http://goodhtml.megauser.com.  In some test cases I have tried it hasn't had the same results as the validator at w3.org.  Certain doctypes it recognizes.  Others it doesn't.  

http://www.yahoo.com/ returns the same results for both.
http://validator.w3.org/ is fine on theirs but not on mine.  It doesn't find the doctype.

Any help in what I need to change or what could be wrong will be appreciated.

I am sorry for the double message.
