VLC can do it, via the Streaming/Saving dialog (the little checkbox in the lower left hand corner in the file open dialog). Click the settings button to the right and you will see the dialog below:
For transcoding settings I did h.264 (he can pick codec of choice) with an avi container and 64 kbps mp3 audio. you can pick a higher quality but it will take longer is all. You might find some combinations messed up, as an example I couldn't make an MPEG 1/2 with a low enough bitrate to encode.
