soon after i submitted this patch, i figured that out, and yes, 
skipping the first frame is a horrible fix... the little 'pop' 
that you are hearing is actually a bug in the 'mp3lib' decoder, 
try with '-ac ffmp3' (after applying my patch) 
and you should not hear it, 1st frame should play correctly, 
(please inform me if the pop is still present in that, 
although it seems fine here)

i'll resubmit the patch with a correct fix for the 'pop' sound

also when you try to seek back to the begginning with the mp3lib decoder, it skips a little too, probably because the 
MP3_DecodeFrame() function has bad hacks, i'll try and fix that too
looks like the mp3lib code is quite buggy,
