I don't suppose you're seeing a message like "A-V delay set to..." at the 
start of the mencoder run?  I've found that at least some versions have 
the irritating habit of (somewhat unpredictably) setting a soft delay, 
which gets lost when the video is extracted.  Does the AVI file play okay?

Also, with recent mkvtools, the video extraction step seems unnecessary, 
and creates extra work for you (i.e. specifying the framerate).  That 
doesn't really help you with the sync issue, though.

IMO, ripping DVDs is often more akin to an art than a science (this is 
particularly true with nasty NTSC discs).  If there's any way to get 
consistently good results without occasional manual intervention, I 
haven't found it.

I usually encode films with -oac copy (mainly because of interlaced bursts 
from dodgy NTSC edits, which cause desyncs even with pullup, but also to 
deal with timestamp wierdness), throw out the audio and sync by hand.
