Extensions need to be lower cased otherwise a suitable player is not found for them

Easy fix here. I found this issue while creating video nodes programatically for files that already exist as attachments to different types of nodes. I found that I could link an existing fid to the video node field fine but it would not play. It turns out that the file extension for the file i l was linking was uppercase . When i added strtolower to the extension in video_helper.inc line 35 it played. So the player is mapped to extension but only lower case map.

$video->extension = strtolower(pathinfo($element['#item']['filename'], PATHINFO_EXTENSION));

Thanks for great module. I posted a how to here for adding existing videos and new videos attached to other nodes to your video library. http://drupal.org/node/860590
