I have a video site and I have submitted both standard and video
sitemaps ( http://www.newbaby.com/video_sitemap.php ) to google.  They
are UTF encoded and are reported indexed with no errors.  I cant seem
to get my videos indexed in Google video.  We have a CDN to house our
actual videos on to make sure they stream at high rates.   I read that
you cant have a different URL in your sitemap so I verified the CDN
site through webmaster tools (rd.newbaby.com).
It appears the only videos to show up in Google Video are the ones not
in my sitemap.  Could it be because the sitemap has a file extension
of .php and not .xml?  Again webmaster tools reports no errors.
