New Video Widget

Is there a way to use the widget system to display new videos?
  1. New can be defined as posted videos in the last two weeks, etc.
  2. We probably will need to use category to accomplish this.
  3. These videos should expire as NEW and give way to current ones.
Can we accomplish this?

isn't this the widget on the left , that can display the newest 5 post in a category. I think the problem is it is not visual, if there is a thumbnail for each purchase post, then I can put the thumbnail .  I have to write some code so can associate a thumbnail that is different than the post imagewe shouldn't use post image since the post already has a trailer, and having both image and a trailer in the post is too busy.  but a video thumbnail image is necessary so it can be displayed in the sidebar or in the product listing feature (not yet)
