The one I liked most was Flash Media Gallery v1.0. This component can be used for displaying both videos as well as images. Categories can be maintained. Another exceptional feature is, the whole component is xml driven making customization simple.

The other components offered http://www.flashnifties.com/ are also good especially the gallery and slideshow plugin.
Another cool site is to visit is http://www.flashden.net/ you must be familiar with stock photos i.e. istockphoto.com this site is in similar lines. The difference is it offers flash components, animations sounds etc… at affordable rates. Some of the components offered are really good. This is a must check out site.
