I don't know if this is part of the issue, but isn't "Pirates" a Disney 
movie?  I know that Disney DVDs are notoriously problematic when it 
comes to PC-based (and especially Linux-based) DVD tools.  Probably not 
the best DVD to test with; the problems may very well be in libdvdread, 
libdvdcss or libdvdmenu.  You might want to scan the lists for thoses 
projects and see if they're having the same issues with that disc (or 
other Disney titles).
