[MPlayer-users] Different Video Length depending on the audio chosen

[Khelben Blackstaff]

Hello.
I tried to transcode one of my dvds to h264 and noticed something which
seems weird to me.
If i choose the AC3 5.1 audio the movie is 6078 seconds long, while if
i choose the DTS 5.1 audio the length is 5971 seconds. Despite the 2min
difference, the movie seems whole.
Is this normal ?
