well it's thanks to Arpi that i found out about the two small libdvdread 
tools. it takes a little bit of thinking to accomplish it but it's fairly 
simple.

1) use title_info to find each title number, which vts file it is in, and 
what position it is in inside it's vts file

2) use ifo_dump sequentially on each ifo file to extract the track length 
of each track inside each vts file

3) take these two data structures and combine them together. resulting in 
a list of track number / length pairs... voila.

nothing else to it really. But i would think from MPlayers point of view 
it might seem a little silly in their eyes, which i think i can 
understand. In this instance though, this is one of the main points of the 
script. I've not had any problems with the dozen or so DVD's i've tried, 
and i've picked screwey ones in particular (i.e. ones with silly games on 
etc...). The only title i couldn't make work was Jurassic Park, but that 
was becuase the dvdread utilities had problems, so my script never got the 
data.

next step for me will be to incorporate chapters in the data i find, which 
is pretty simple too.
