> I've dug into this error, and as ugly as the assert() statements are, they aren't the real reason why libdvdnav is crashing. What's actually happening is that the vm->state.domain value is being changed silently from DVD_DOMAIN_VTSMenu to DVD_DOMAIN_VTSTitle. This means that the "program chain number" (I think?!) of 15 is being validated against pgcit->nr_of_pgci_srp == 1 instead of pgcit->nr_of_pgci_srp == 30. set_PGCN() then complains and the assert() fires.
Who is changing this value?
> So I've hacked together a quick fix (attached; against libdvdnav-5.0.3), which works for the "Red Dragon" DVD.
Not sure it's the right one, tbh.
