try Freeware: FFmepg, Handbrake and Freemake are all good selection, completely free and no other cost. Handbrake has both windows and Mac version. all great for converting avi to mp4/avi and other foramts, and rip dvds for all users. have a try. and some rechargeable software such as iVideotool Video Converter(http://www.ivideotool.com/video-converter.html) may much better for converting and compress videos
