If you are willing to spend some time learning, i would suggest ffmpeg. It took me a long time to learn it, but i'm very glad that i did. It's a command line tool, and is very powerful. I personally prefer to convert everything to OGG (theora+vorbis) with it, that actually ensures the support of freedom in the codec themselves.
