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.
