As an Admin, I promote the uploading of images to a Picture LIbray on our SharePoint Intranet, so my Users can do slideshows and keep their files organized.
When it comes to videos, I tell them to upload to a Document Library.
1) Is there a Web Part to get a true "video library", with some video interface controls?
2) Is SharePoint compromised when there are a lot of videos on our Intranet? Is is better to have the videos hosted elsewhere and link to the Intranet?
