I can answer some of your questions.
1. When you "Save as a Web page" in Publisher 2000, the html coding
engine
would automatically resample and resize oversized and high resolution
images
to 96 dpi. With Publisher 2007, you have a new html coding engine, which
has
been tweaked a bit since Pub 2003, and a "Compress graphics" tool has
been
added. Once you run the compression the inserted images will be resized
and
resampled much as you saw in Pub 2000, and your overall file size will
drop.
This tool has been improved since Pub 2003. Also the VML option was
dropped
in Pub 2007, which greatly improved cross browser compatibility.

2. I have to guess on this one, but the MSO file is probably a result of
importing the Pub 2000 file into Pub 2007, and bringing with it some of
the
old code from Office 2000. Did you insert any Word 2000 text into your
Pub
file? However, it is possible that is in the way your are producing the
file...do you "publish to the web" to produce your web files? I can't
reproduce your issue at this point.
3. The WMV files are usually a result of clip art conversion to HTML.
They
aren't really media files as you understand them...a bit deceptive. The
clip
art part of Publisher was changed as of Pub 2002 when Publisher was
"adopted" into the Office family. Not a good switch in my mind, but
others
would disagree. If you use FireFox view your site, right click a page,
and
choose to View Page Info, and then look at the media tab. You can scroll
down all the image on your site and find on of those wmv files and look
at
it...I would imagine it will be a piece of clip art.
4. If you don't compress your images using the compress graphics tool,
the
html coding engine will make multiple copies of your images in various
formats including PNG. Run the compress graphics tool and the PNG files
should go away.
Go back to Pub 2000? I still prefer Pub 2000, but there are advantages to
using 2007. You can't layer design objects in Pub 2000 without them being
combined and converted into gif files. Pub 2007 offers you more
flexibility
in design. Pub 2000 produces cleaner, and simpler code and thus less
weight.
There are many pros and cons both ways, but before you go back try the
suggestions above, and you might be happier. Also, you can run both
versions
on your computer. If you reinstall Pub 2000, just do a custom install,
and
install it in its own folder rather than the default. You don't want to
overwrite Pub 2007.
Hope this helps.
