Walter, any resolution in this case would be to add a feature to automate the duplicate menu creation that is necessary in order to represent something that the DVD-Video specification does not support.
In DVD-Video, button highlights and subtitle tracks are limited to a 2 bit graphics layer. It’s impossible to get full fidelity on highlight layers which don’t meet these requirements.
Creating duplicate menus, then using the auto-activate feature is one way to get around the limitations of the format – it gives the appearance of 24 bit button highlights, but it’s only a fudge. DVDSP does the fudge behind the scenes, taking out the hard work of manually wiring up the menus. But this workaround (whether manual or automatic) is a workaround for the very limitations of the DVD-Video specification.
One drawback to this workaround is it will not work as expected in a software DVD player – the user will have to click the button to get the “over highlight”. Another drawback is less capable DVD players may show a noticeable delay when going from one menu to the next that displays the “over highlight”.
Like most workarounds, it’s imperfect.
In my humble opinion, working within the limitations of the spec is a cleaner way to work – but that’s just me.
