How to download videos to your so that you can watch them on your iPod Touch.

1. First you have to ensure the video is in one of the formats supported, MPEG or MP4. The videos you can purchase via iTunes are all in these formats. If you have another format like AVI or WMV you wish to use, it has to be converted to MPEG or MP4 first.

2. iTunes needs to be used to transfer the video file. On the left side panel under Library, they are under the Movies and TV Shows options. Connect your iPod Touch to the computer, then drag and drop the ones you want to the iPod Touch under Devices on the left side panel.

Videos that are not listed in iTunes can be dragged from any folder on your computer and dropped to the Movies section in iTunes. From there, you can drag and drop the videos to your iPod Touch.
