I don't at all object to the complexity of the settings. (Or, I do in a more limited way, but that's not the point of my comment.) I'm disagreeing only with the parent's suggestion that all experiences with VLC are very simple.
On your point: I think having many settings, including very technical ones, is great. I think putting no thought into how to present them clearly is not. Documentation does not to my mind excuse poor interface.
Honestly, I love that about VLC. There are plenty of shell commands I have no idea how to use properly, for instance, but knowing that they are there if I ever do need to learn how to use them is great. The modern theme of stripping out functionality in favor of perceived simplicity undermines these great comprehensive tools like VLC. If you don't know what a setting does that shouldn't be a problem; you probably never have to touch it then. Sure, some of the functions seem pretty old school today, but I'd hate to see VLC dumbed down.
