As Shaun said, it never worked for me neither. One solution is subdelay, but
I don't like it. Actually, before rip the movie I run chaplin, for example

chaplin -t 1 -p 2 

This ask to the program  split (in chapters) title 1 in two pieces of the same
length approx (is not exact because it honored the chapters)

With this info, I rip in two parts mplayer -dvd 1 -chapter 1-N etc. and
mplayer -dvd 1 chapter N+1-M etc. 

Now I supppose you've ripped your movie in one or severals files. Try to find
in the vobs the exact point where begin the second avi and split the vob there
(well this demand a lot of trial & error, another possibility is split the
vobs in two groups and mencoder again). Group the vobs belonging to the second
avi and vobsub again ....
