is there a logical reason why default setting for allow OUP in IFOs is off, but allow in VOBs is ON ?

or have a screwed up my settings and am not seeing the real defaults.

I checked them today because I noticed that some copies would not fast forward through opening sequences & would not let me skip ahead to next title / chapter.

how should these 2 settings be, for maximum user control ?

so are the program's default settings the wrong way around for normal use , or have I lost track of what the original defaults were?

hi cybemole the default settings are, ticks next to each of following:

Remove UOPs (user operation prohibitions)
remove UOPs from ifo files
remove UOPs from vob files

thanks - and with those default settings you should always be able to fast forward and/or skip to next title or chapter , even where the original DVD would not let you - like on warning messages ?

I made some copies (DVD to DVD - customised) that won't let me do that, but maybe I did not have all of the boxes ticked.

Typically, I still have to watch the short warning or initial title section for a minute or so before I can use navigation controls.
