#164 .VOB playback out of sync

I have a .VOB file that keeps getting out of sync. I
can identify the locations where it goes out, but the
milliseconds of out of sync seem to stack up until it
becomes anoying to watch. (hence adjusting the audio
time shift doesn't seem to help in the long run)
Everybody else seemed to have a problem related to
other formats like DIVX however my problem is on the
unadulterated .VOB file itself.

I did find a thread of somebody that uses the
Play>Filters>Audio Switcher>Audio File 1, but this
seems to fast forward the video to a not to distant
location in order to re-sync.

What I don't understand is that the statistics see
the time shift before it happens, isn't there a way
to buffer the adjustment on the fly?

    If Im right, the buffering for dvd playback is done by a
    filter, not by MPC.

    What kind of PC do you have? Hardware spec and OS. What
    filters are loaded when you play that vob file?

    I'm not sure what you mean when you say filters. I went
    into the filters section of MPC and the only thing that is
    relevant to the filters is the audio files located in the
    file folder with the .VOB file. Is there a setting in the
    Options section that needs modification?

    So you use external audio files (wav,mp3,ac3,dts,etc.) with
    vob files, and the external audio files are out of sync?

    Your hardware is ok.

    The audio does not seem to be seperate from the VOB file,
    at least it doesn't look that way when I go to the filters
    menu under audio. In the file folder the VOB is there are
    a couple of files which I have listed. I don't think
    these are used for audio with the acception of the VOB
    file.

    VIDEO_TS.BUP
    VIDEO_TS.IFO
    VTS_01_0.BUP
    VTS_01_0.IFO
    VTS_01_1.VOB

    Yes this is a simple dvd format.

    This is the only dvd that getting out of sync for you?
    This is a single vob (video object file) file, that contains
    the video stream, audio streams, chapter information, and
    subtitles. Try to open the dvd (the video) by opening the
    VIDEO_TS.IFO file not just the VTS_01_1.VOB. If you elready
    did this, try the other case (open the VTS_01_1.VOB directly).

    I don't really know what can be the problem.

    Can you send in here a screenshot abot this: "the statistics
    see the time shift before it happens"?

    Here is the screenshot with the statistics. I went
    straight to one of the parts that it skips and captured
    it. Sure enough the Sync Offset shows the time shift.
    What I don't understand is why MPC doesn't have something
    to adjust for this on the fly. If its measureable can't
    it be adjusted and fixed on the fly?

    I said skip, it doesn't actually SKIP it keeps going but
    the audio gets out of sync.
