sorry if this has been posted somewhere else......

i have a non-copyrighted DVD that has a ac3 file but the audio is real low, when played back on my standard player....

i successfully demuxed the audio and then adjusted the volume of the file to where i can hear....

problem is when i mux them back together to a mpeg 2 or vob the audio is out of sync about 2-3 secs....

once i have the file on my hd i insert into editor adjust volume export back to the original file settings; 48,192,stereo or 1536 for wav file

before i do any editing the dvd plays fine on both my standard player and my pc dvd rom....

just after i do the editing....any help would be appreciative
