hi i converted a mkv (matroska) file to avi using ffmpeg:

ffmpeg -i input.mkv -f mp4 -vcodec mpeg4 -sameq -r 29.97 -b 512kb -acodec ac3 -ab 128kb -vol 512  output.avi

the output file plays fine using mplayer.

after that, i using mencoder to insert subtitles:

mencoder output.avi -o new.avi -oac pcm -ovc lavc -subfont-text-scale 3 -sub subtitle.srt

however, after i play back the video "new.avi", the video and audio is out of sync. What options can i put into mencoder to sync the A/V. ?

I have also tried ffmpeg -newsubtitle option but can't get it work. Any examples of usage of -newsubtitle would be greatly appreciated. thanks
