If Stacking is turned on in My Videos, stacked files will be handled as a single file. If this is not checked, XBMC will handle the stacked files as a playlist.
Auto resume from last position
When enabled, XBMC will automatically resume videos always from the last position that you were viewing them, even after restarting the system.
Note: You can also start a movie from the last stopped position by opening the context-menu on a movie file (white button on the gamepad) or by just clicking the "Play" button on the remote without the need to have this option enabled.
Enable Autoswitching to Thumbs View
Can be used to automatically view the contents of a folder in the thumbnail view when 50% of all the items (files and folder) have thumbs.
Use Large Icons
Will use large thunbnails, as opposed to normal-sized thumbs when autoswitching.
Clean Library
This item will perform a number of 'cleanup' tasks on your video database and should be run if you have removed or renamed the physical files after a database scan. Tip: XBMC puts a video in it's database if you change any OSD setting while watching, also resume points are stored here.
Removes any videos with invalid paths + all information tied to these files.
Removes all removable media (example: DVD) without checking for existance + all information tied to these files.
Controls the resolution at which video is displayed. It causes XBMC to upsample / downsample the video to the selected format.
Framerate Conversion
Allows you to play PAL videos at NTSC framerates and vice-versa
Flicker Filter
Sets the amount of flicker filter applied while videos are playing. We recommend you keep this as low as possible, and for best possible quality set it to 0. Defaults to 1.
Soften
Denotes whether the soften filter is applied during video playback. It is recommended that this is set off for optimal quality. Defaults to off.
