Hello,
I tried to convert SVCD to DVD but could not get audio to sync properly with 1 certain file. I used same method as per all other files but with this 1 the sound just lagged behind and the picture become jerky, stall and start all the time. Here's the log from BBmpg for the 1st cut:

NOTE: The resulting file may not play back correctly.
Try reducing the video bitrate or increasing the video and
audio startup delays.
