This has been discussed before as well ... I forgot the exact technical
reason why, but MP3 and Vorbis are too different - it's not possible to
transcode without completely decoding MP3 and re-encoding with Vorbis.
This is also the main reason why it's "evil", there is just no other way
than the way of the Poor Man.
