Hi,

I don’t know if this helps, but I’m getting the same errors as you do when I decode small mp3 files who is just a part of a song. My experience is that these errors does not effect the decoded file. Have you tried to play the decoded .pcm file? I do so with Audacity (http://audacity.sourceforge.net/, I import .pcm file as raw audio data in the project menu) and I can’t say there is anything wrong with the decoded file, at least from just listening to it.  

Regards,

H.
