I think we/you got it now! :-)

I did this in the httpd.conf:

Commented out this in the genaral sections
# AddType application/x-gzip .gz .tgz

Made the directory look like this:

<Directory "C:/Engineering/Projects/XMLTV/XMLTVTestsite">
    Options Indexes MultiViews Includes
    AllowOverride None
    Order allow,deny
    Allow from all
    AddEncoding x-gzip .gz
    AddType application/xml .xml.gz
    AddType text/xml .xml

And now the headers become this when I access a xml.gz link:

HTTP/1.x 200 OK
Date: Sat, 14 Jun 2008 16:55:40 GMT
Server: Apache/2.0.54 (Win32) PHP/4.4.7
Last-Modified: Thu, 12 Jun 2008 22:18:16 GMT
Etag: "5ac36-159b-89b5a184"
Accept-Ranges: bytes
Content-Length: 5531
Keep-Alive: timeout=15, max=100
Connection: Keep-Alive
Content-Type: text/xml
Content-Encoding: gzip

And FireFox displaye the *contents* of the gz file rather than offer
to save it!

A *really* great THANK YOU! for helpong me out!
