My favourite audio/video transcoder is MediaCoder. It's free, an active SourceForge project and, most importantly, quite good.

It runs on Windows, and (using Wine) Linux or Mac OS X.

Why not give it a try and see for yourself?

The project's home page is:

Thanks Bassism and Shinko, whoever you are.
