MediaCoder is the best program to convert audio and video files. The best of all, it is opensource! This program gathers the best and most popular video and audio codecs so you can convert pretty much any media file into (almost) any format.

You can convert files to your video iPod, cell phone, PDA, PSP, ou choose other formats store on your computer.

MediaCoder is Windows program but you can also run it on Linux through Wine. Initially, the program might seem a bit complicated but browsing through it a little you'll find it to be incredibly easy to use. For a simple file conversion you can just choose the audio and video encoder, everything else can be left at default. You can also download other extensions to have an automatic conversion process to your portable devices such as cell phone, PDA, or PSP.

Besides converting media files, you can also add subtitles to your movies, reduce the length of the file, extract the audio track from videos, or reduce the movie screen size.
