I am running into trouble converting some SVCDs I have to VCD format. I do the following:

In TMPGenc:
- Demultiplex SVCD MPEG2 file into separate audio
and video stream using MPEG tools.
- Load m2v Videostream and mp2 Audiostream into
TMPGenc and convert to MPEG1 using standard VideoCD
template

After this the audio is way out of sync. I tried multiplexing again, converting just the videostream and multiplex with original audio.. no sigar..

any help appreciated!
