HandBrake

HandBrake is a great application for converting videos or DVD's into whatever format you require.

I use Handbrake primarily for backing up my DVD's into MP4 format, so I can play them on my Macbook, AppleTV, or iPhone. I also use it to convert .avi or .wmv files that I come accross from time to time.

It is available for Mac or Windows
