/*########## Dirty ThumbnailCreator Script by MonsterMagnet ################################################
############################################################################################################

### Best viewed >= 1024x768

### Requires Avisynth 2.5 (http://sourceforge.net/projects/avisynth2/)(tested with 2.56 and 2.57)
### and mplayer2 (included in WinXP C:\Programme\Windows Media Player\mplayer2.exe).

### This script creates thumbnail and preview images from your movies, for use with Mediaportal.
### Only missing thumbs or previews are created.(so you can run this script every time you add new movies !)
### 100 movie thumbs and 100 previews are created in 3:10 min (Athlon64 3500).

### TIP 1: Try this script with a test movie directory.
### TIP 2: You can use this script inside Mediaportal with the MyPrograms plugin.
### TIP 3: In directory: C:\Programme\Team MediaPortal\MediaPortal\Skin\BlueTwo\myvideo.xml change 
###        <import>common.facade.video.xml</import> to <import>common.facade.pictures.xml</import> 
### TIP 4: Eventghost.org (open-source automation tool for MS Windows, supports infrared or wireless remotes)
