This is the best application I have found for converting video formats from virtually anything to an iPodcompatible format.

MoviePod saves you the trouble of having to manually convert your movies in order to play them on your iPod. With MoviePod, converting a movie takes a single Drag & Drop.

MoviePod supports every common movie format* (MOV, MPG, AVI, ASF, WMV, VOB, DV, FLC and QuickTime plugins) so you can easily get your movie collection onto your iPod.

You can queue up as many movies for conversion as you like and when you return, MoviePod will have them all ready to go on your iPod.
