bad main-data-begin pointer?

Hi,

   I am using libmad to handle mp3 access for my project ( www.xbat.org ).
Our particular application requires fast, accurate seeking, and I have been
successful in using header information to seek to the correct frame.  I am
having trouble, though when I set the decoder (from the "high-level" API)
running.  For many files it works fine, but for some, I get "bad
main-data-begin pointer" errors for the first one or two frames decoded.
  Right now, I am circumventing the problem through the use of the
MAD_FLOW_IGNORE symbol in the error callback function, but this results in
the somewhat-undesirable behavior of decoding zeros for the first several
frames.  Is there a way around this, short of deliberately seeking several
frames early and then discarding the unneeded data?  Might this have
something to do with bit reservoir encoding?  Any help would be much
appreciated.

Thanks,
Matt
