I'm not sure if my source audio is necessarily DTS or not.  However,
I am having significant troubles getting consistently good, properly
sync'ed rips.

I don't have anything in particular to offer, except the threads
I've started elsewhere trying to figure this out:

    Doom9's Forum: "mencoder, x264, vorbis, matroska - bad a/v sync
    problems"

    mplayer-users: "mencoder + x264 + pullup, softskip = a/v sync
    problems"
    http://lists.mplayerhq.hu/pipermail/mplayer-users/2007-February/065674.html

My latest experimentation has shown me two things:

    (1) some of my *source* material appears to be out of sync
    (2) using bframes=0 in -x264encopts seems to help or all
        together eliminate the sync problems (at a definite hit to
        quality, though)

Hope this helps.  Please report back if you make any progress!
