It's a very small plugin (around 160 kb) and should only take a minute to install. There is a version available for Netscape, Internet Explorer and the AOL browser. Flash is already supported by WebTV.

If you are using Netscape 4.0 or IE clicking on the button will let you automatically install the plugin. Other browser may need to be restarted after downloading. Internet Explorer users can enter the site directly, IE will automatically install and configure the plugin for you.
