1)Make sure you have updated your QuickTime software to version 7.0.3 or later. If you don't have QuickTime 7.0.3 installed, get it now.
2)Open QuickTime 7 Pro.
3)Choose "Open File..." from the File menu.
Select the movie you'd like to play on your iPod, then click the Open button.
4)Choose "Export..." from the File menu.
5) Choose "Movie to iPod (320x240)" from the export drop down list and click the Save button.
The Export progress bar shows you how much of the export process is completed. The longer your movie and the larger its frame size, the longer the export will take.
Once the export is complete, QuickTime Pro will place on your Desktop a new version of your movie that will play on the iPod. Double-click the new file and play it to make sure it looks as you expect.
6)To get the movie onto your iPod, open the file with iTunes.
7)Transfer it to your iPod.
