Q. how do i find DVD section

From the homepage, you can click on the link for "Catalog".  Under the search options, you can click on "New Items".  This will give you the option to search only new DVD's for the past few months.  You can also do a Keyword search for "DVD'.

You can search for a particular title or director by going to the "More Search Options" tab and selecting "DVD/Video" from the "Popular Collections" list, and then doing a keyword search for that title or director. This may return some VHS items, but the format is listed in the search results, so you can easily tell whether or not the title you want is available as a DVD.
