...it's not clear what makes you think the wizard forces you to enter anything you don't have and don't need.
Maybe because it comes up automatically on the first run, and the OP doesn't see the Close and Cancel buttons?
Also, if they just blindly click through and don't read to understand, all bets are off.
don't let the wizard dissuade new users.
If OBS were a simple "launch and use" thing, then only a handful of people would ever find it useful. The reason it's popular enough for you to find it in the first place, is because it serves a wide variety of unique applications, which also means it must be configurable to suit each one. If you get hung up on the configuration, are you really qualified to stream at all? (without a separate tech person to do it for you)
The wizard does an awesome job of hiding the gory details - if you pay attention and give it the right information: "garbage in, garbage out" - but if you get hung up on *anything at all* beyond "push button, get stream"......well......see the previous paragraph.
