# Navigation / Share Settings

## Thumbnails

Thumbnail seeking position (in seconds)
  Most video files begin with some seconds of a black background before the movie starts. You can set the time in seconds for the video thumbnail position.
Use MPlayer for video thumbnails
  The external program MPlayer sometimes yields better results for thumbnail creation than the default thumbnailer, so just try it.
DVD ISO thumbnails
  Create thumbnails for DVD ISO-images
Audio thumbnails display
  You can choose the behavior for audio thumbnails; search for alphabetical thumbnail pictures on the filesystem, or let UMS download album art from coverartarchive.org

You can browse the cache in a virtual folder on your PS3 after scanning.
