iPodRobot Video Converter is a free tool which can convert various video file formats into MP3/MP4 for playback on iPod and iPhone.

The software is capable of converting almost every video format out there including DivX, XviD, MOV, rm, rmvb, mkv, MPEG, VOB, DVD, WMV, AVI, AVS, ASF, H264 and more. It quickly converts the files to MP3/MP4 format with high quality output. Additionally, it has an integrated MPEG4 codec which speeds up the conversion process even more.
Another handy feature of this software is the option to merge many video clips into one. This is incredibly useful if you are working on a project that requires multiple clips to be combined into one. Furthermore, it has the option to preview the video in real-time, so you don't have to wait until the entire conversion process is complete to see how the final video turns out.
The user interface is also quite impressive. It is skinable and very easy to use. You won't have to struggle to figure out how to use this software. It's straightforward and practical for anyone to use.
Overall, I highly recommend the iPodRobot iPod Video Converter software to anyone that is looking for a reliable software to convert their videos to MP3/MP4 format for their iPod or iPhone.
