At least, all VLC callbacks should have been registered. The vout window provider can be triggered at any time after OpenIntf (even before application:WillfinishLaunching or similar), so important initialization need to happen earlier. So in fact, the main window needs to be there, if we want to have embedded video playback.
And we need to load the main window anyway right from the start - without it VLC is unusable. So I see no reason to artificially delay its loading...

Well we need an existing parent view for the out window provider. So its not only about helper classes, but about the UI content itself. But you are absolutely right, the xib should contain the UI and not any other important objects like VLCPlaylist...
I would say, first make the init order right (see above points), and afterwards we can think about optimizations by lazy loading.
