ok, the problem is that xmlto fails to get docbookx.dtd (well,
actually, it's your xml validator that fails to do that, but that's
not really the important part).
Did you install docbook-xml package?
Do you have /mingw/share/xml/docbook/schema/dtd/4.5/docbookx.dtd?
Do you have /mingw/share/xml/docbook/schema/dtd/4.5/catalog.xml?
Do you have /mingw/etc/xml/docbook-xml.xml?
If you do, does it have the following line in it:
  <delegateSystem
systemIdStartString="http://www.oasis-open.org/docbook/xml/4.5/docbookx.dtd"
catalog="../../share/xml/docbook/schema/dtd/4.5/catalog.xml"/>
?
Did you install libxml2 package?
Do you have /mingw/etc/xml/catalog?
If you do, does it have the following line in it:
  <delegateSystem
systemIdStartString="http://www.oasis-open.org/docbook/xml/"
catalog="./docbook-xml.xml"/>
?
Do you have /bin/xmlcatalog.exe?
