1) Create a new folder named Demo Mode on the iPod.
2) In iTunes, rename any video file as Demo. When your iPod is charging and left untouched for two minutes the movie you renamed "demo" will play and repeate. Just like a screen saver.
Notes:
1. It only works on 5th generation Video iPods.
2. You must have enabled disk use checked.
3. You must have the most up-to-date firmware.
4. The iPod must be charging and on pause or not playing.
