Yes, this is a feature. Unfortunately it's not perfect, but personally  
i kinda like it.
It's not the first title it skips btw. it depends on what is set as  
root menu of the DVD, and what as title menu...

Yeah, some DVDs have this, it's not something that we can solve as far  
as I'm aware. It has to do with how the menus are designed. (remember  
that you usually use a remote with a DVD).

DVDCSS fails, something like this can happen. Hard to reproduce of  
course since once you set a region, you are stuck.....
