You can import videos into iTunes; it just takes a little extra work. Unfortunately, you cannot just drop files that you have download from the Internet or uploaded from a camera into iTunes. Most videos found online or that come from video cameras are in the .avi, .mpg or .wmv format, and the iPod only supports MP4 format.
This does not apply to video content that is directly purchased from the iTunes Store. This content is immediately playable on iTunes and iPods, as is anything made with QuickTime in an MP4 format (.mov, .m4v or mp4).
To get video into the proper format, you'll need to convert it with Quicktime 7 Pro. You can also convert videos with iMovie and Final Cut Pro.
If you do not have access to QuickTime, you can use one of the utility programs that are available, such as Videora iPod Converter 2.5 for Windows. Utility programs contain a file-conversion wizard that is easy to use. It will convert the file to an MP4 format and automatically resize it so it displays correctly. This means that your converted video will have the best aspect ratio and resolution for viewing on an iPod.
Other video converters are available, like Cucusoft's iPod Video Converter and the Next Video Converter. Next Video Converter has a simple interface that allows you to convert DivX, XviD, MOV, RM, RMVB, MPEG, VOB, DVD, WMV, and AVE to the MP4 format.
