    What this means is that the audio & video packets should have similar timecodes for packets that occur at the same time. This is normally taken care of by the encoder so you shouldn't have to do anything. Any alignment problems are normally caused by the encoder sending packets late or getting the timecodes wrong. Small amounts of misalignment can be handled with sort buffers but larger problems need to be rectified at the encoder.

    See Advanced nDVR Configuration for settings.

    So what Wowza can do in the problem is to adjust the dvrPacketSortTime and no others?
    any suggestion or experience sharing on adjusting encoder setting to avoid this unaligned problem ? I do not really understand why the timecode would be error
