Is there a way to build HTML page so the sitemap generator will create <video:tag> and <video:duration> tags?
If A1 Sitemap Generator does not pick up videos, please PM/email your website address, and I will take a look. A1SG should pick up all videos no matter if you use Javascript, HTML or whatever to embed your videos! (Try 3.2.0 if you. It added support for more "Flashvars".)
<video:duration> is not currently supported... But I implement what my users/customers want, so if your website contains duration information, I will see if I reasonably fast can add support for i in video sitemaps :)
