Thanks,

I can make a API of it if you like, i.e. split the guess part. If you want you 
can import the dvdbackup program to mplayer. I have it in CVS (Some bug fixes 
made) just see the http://sourceforge.net/projects/dvd-create/ . Please let 
me know what interface you want for the guess function.

Yes, the code could be improved it was just a first shot of a guess algo. When 
I get the VMG_TXTDT_MG structure solved it could be a really good one (see 
below).

Yes, on some DVD has it but mostly not. You will find that e.g. Sony makes 
DVD's with VMG_TXTDT_MG structures in the VIDEO_TS.IFO - however mostly it's 
just the title name info and info about the other titles on the DVD e.g. 
directors comments etc. Anyway I'm currently solving this structure it's not 
that well documented and dvdread doesn't export it - although when I'm 
finished it will :).
