Which brings me to a side-note. IMO, DVD navigation/players were the worst implemented invention of the 90's. Everything from their remotes to disc layout sucks balls.
And who would have imagined that blu-ray would be even worse. My blu-ray player remote has no less than three menu buttons.
I still have little idea which of them I need to press at which point to get back to the previous menu. I press the wrong one 80% of the time

A couple of blu-rays that I got recently came with multi page booklets to explain how their overly complex menu systems worked !
There is one improvement, at least blu-ray player menus respond much faster than DVD ones did.
