This is the mencoder output showing it selected [mp3] audio codec:

==========================================================================
Opening audio decoder: [mp3lib] MPEG layer-2, layer-3
MP3lib: init layer2&3 finished, tables done
AUDIO: 48000 Hz, 2 ch, 16 bit (0x10), ratio: 32000->192000 (256.0 kbit)
Selected audio codec: [mp3] afm:mp3lib (mp3lib MPEG layer-2, layer-3)
==========================================================================

Does that mean mp3 or mp2?

Cool, I have ffdshow already .. just gotta figure out how to configure 
libmad ..

Also, is it possible to do a perfect mp2 to mp3 transcode? If so, how? 
If not, what's the closest?

Thanks heaps ..
