SVCD Sound Synch Problems With TMPGENC

[cumminc]

Being fairly new mastering or even understanding TMPGENC was a major task. With the help of the forums i have managed to overcome most of the basic video problems but now my last hurdle to which i cannot find any help topics is a strange synch problem.

With an XVID film i changed the 4cc to divx and ran it through VDUB freeze. There were no frozen frames and no errrors. The sound in the original file is ok. After converting to SVCD i find the sound starts in synch but drifts. Then the video seems to freeze for a microsecond and the audion is either in synch or just out. The drifting and correcting continues and is impossible to correct using any methods explained on any helptopic.

The original sound is48,000 compressed with an MPEG layer3 codec and the video is DIVX5 23,976 FPS. Last attempt was to extract sound and video using VDUB and pull them together in TMPGENC but i always get the same problem. Think i covered everything and gave enough info, hope you can help me

decompress the audio to PCM
then either:
* encode the audio to MP2
* demultiplex the MPG you've created and multiplex the M1V video with the MP2 you've just created

OR

* load the decompressed audio into TMPG
* load the original video file into TMPG
* encode

I had problems with some SVCDs with drifting sync and video pausing whilst audio catches up.
My problem turned out to be mystandalone Philips DVD player. It doesn't like SVCDs encoded at the max bitrate. Even though a movie is constant max bitrate the sync problem would come and go thru the movie but always in the same place if watched again.
Probably no help, Just a thought.
