[MEncoder-users] Convert DTS audio to AC-3 in mkv file

[Pedro Abranches]

Hello everyone.

I have a 1080p mkv file with DTS audio and I need to convert it to
AC-3, maintaining the original video codec and quality.

I'm trying with the following command:
   mencoder video.mkv -o video2.mkv -oac lavc -lavcopts acodec=ac3 -ovc copy

When playing the new file with mplayer it plays correctly, but when
reading with other players like Totem and VLC it doesn't.
What am I doing wrong?

Thanks,
Pedro Abranches
