Can someone help me figure out why when I combine SVCD mpegs with TMPG, I lose audio sync?  I have tried using M2-Edit and TMPG 2.56,57,58.  I still have the same result.  I have also tried on different machines. First MPG plays fine, and then when it goes to second or third the audio is out of sync.  Also If I try to trim off end audio for overlap it loses sync also.  My goal is to take multiple MPGS and combine,demux,re-encode audio, and burn to DVD with Maestro.  Any help would be apreciated. Thanks
