OK ... now I've the feedback I missed.  Therefore I've
uploaded a new bitstreamout version 0.50 at

       http://bitstreamout.sourceforge.net/

with the following changes:

  - Fix bug in MP2Decoder::pushData(): use stream not m_stream
    for sync start check.
  - Enhance MP2Decoder::pushData(): return the used data length
    to be able to increase the data pointer address. This helps
    to avoid to skip buffer of the overrun at start time.
  - Fix bug in mp2.c: Be sure that buffer is only refilled if
    really emptied.
  - Fix bug in channel.c: do not clear boundary flag at the end
    because data frames in payload may overlap (MP2 audio)
  - Enhance STC/PTS check by using a timer of 2 seconds
  - spdif.c: Audio/Video delay can differ upto two GOPs which is
    upto one second for PAL.
  - Fix the changes for ALSA lib 1.0
  - Try to make it work with VDR 1.3.0

In short:

 * For the user of bitstreamout without connected S/P-DIF out from
   DVB to sound card: MP2 audio can be heared without shutter.
 * AlSA (lib) 1.0 works out of the box.
 * A/V synchronization seems to be more reliable.
