Maybe Apple’s better with video formats nowadays, but Quicktime sure used to be plenty obnoxious. There are still a couple of old PC games out there that require Quicktime and are likely to complain mightily unless you have exactly the right period-correct version of Quicktime installed. What a relief in the latter days when Quicktime Alternative became available and you could at least get the necessary codecs without wrangling Apple’s installer.
Of course, I suppose RealPlayer wasn’t much better at the time.
