Bernhard and Chen,  

    Here is what I did, for example, 

    I have 3 separate video and audio files.   

        Video 1.MPG             Audio 1.WAV
        Video 2.MPG             Audio 2.WAV
        Video 3.MPG             Audio 3.WAV

    Each MPEG 2 file has added sequence headers in
front of each GOP for record to DVD.  Each Audio file
was compressed from WAV data with identical header
files.  I can NOT concatenate the video or audio files

before multiplex with timing and limited space.  So, I
have to do

        Mp2enc < Audio1.WAV -o Audio1.MP2
        Mp2enc < Audio2.WAV -o Audio2.MP2
        Mp2enc < Audio3.WAV -o Audio3.MP2

        Mplex -f 9 Video1.MPG Audio1.MP2 -o TempMplex.MPG
        Cat TempMplex.MPG >> Mplex.MPG

        Mplex -f 9 Video2.MPG Audio2.MP2 -o TempMplex.MPG
        Cat TempMplex.MPG >> Mplex.MPG

        Mplex -f 9 Video3.MPG Audio3.MP2 -o TempMplex.MPG
        Cat TempMplex.MPG >> Mplex.MPG

    The result Mplex.MPG can NOT be recorded to DVD. 
I looked at the video files using MPEG inspector,
Video*.MPG are the right format with 15 frames / GOP. 


    Is there any time stamp issue or something? Can
anyone let me know what is the "single pass" is about,
sorry, I'm new to this. 

thanks, Cindy
