audio sync problem in converting

I am trying to convert some videos using SUPER video converter but after converting I notice that the audio is out of sync and gets worse gradually as the video goes on.
In SUPER I'm setting the output container as 3gp so I can put it onto my Nokia Xpressmusic 5800. The video files were originally in mpeg format and worked fine.


Any help would be greatly appreciated. Thanks

 

Try XviD4PSP.
Drag the source onto the window.
Set the format (left side of window) to 3GP and on the top menu, click 'Encode'.
Good luck.
