It really isn't the same thing. For example, lame and mpg123 are
substantially different programs. One is capable of encoding mp3 and the
other of decoding mp3.

This is an example of mencoder decoding a real stream, not encoding one.
Sorry, I guess I'm being a pedant here. I imagine what fuzzix meant was
that if mplayer can decode it, mencoder can decode, transcode or re-encode
it to something which it can encode. I don't think it follows that it
could encode anything it can decode though.
