Hi,

I'm looking for a tool to convert directly an mpg file to ac3 file ( for the audio) and m1v file ( for the video). I want to do this to us them in DVD Authoring.
I'm asking that because , each time i try to first demux to m1v+mpa then convert the mpa to ac3, there is always some different duration between the m1v and the ac3.

thanks for your help

Benjamin
