You can automatically play all videos, music, or photos at any category level and below. Navigate to the category level you want, and press the Play button instead of the Select button on the remote. Instead of playing a single item, every item at the current level and below will be played automatically. For videos, every video at the current level and below will be played one after the other, for music, every song in every album at the current level and below will be played, and for photos, every photo at the current level and below will be shown in the slideshow.
This can be used create playlists of videos, music, or photos. You can even create playlists of your playlists if you already have playlists created. You can also randomly and continously play all of your Christmas songs, for example, for hours of Christmas music.
