... whats about the audio/dd frames between cutOut mark
upto the point where the video PTS at cutOut reach the
audio/dd PTS?  Shouldn't those ones be included or
replaced with silence:

                           commercial
  video  ----------------%************%-----------------
  audio  ----------------%--|*********%**|--------------
                         ^            ^
                       cutOut       cutIn
                         ^^^^
                         audio PTS delay

?
