Thank you for replying so quickly.

Both "mplayer -identify -frames 0 dvd://1 -aid 128" and
"mplayer -identify -frames 0 dvd://1 -aid 137" report the following.

ID_DVD_TITLE_1_LENGTH=6078.840
ID_LENGTH=6078.84

So, i guess the correct duration is 6078 seconds, but when mencoder
finishes the transcoding the resulting file has 6078 secs if it has ac3
audio and 5971 if it has dts.
