By DirectX, I'm assuming you are referring to DirectShow. What sort of "common" things are you trying to do? Just play back a movie?


I'm an experienced Windows programmer who is now learning to come to grips with Mac OS X and QuickTime. I've created many DirectShow applications and "filters" (which are the components used within DirectShow) and also a few Windows Media applications. I'm now developing a QuickTime plug-in. From what I can tell so far, QuickTime is probably on a par with Windows Media in terms of difficulty, and a lot easier that DirectShow filter development. When it comes to just playing back a movie, all three architectures are I've found are quite straightforward.

Is there some answer to my colleagues on the Windows side about why many
things are so difficult in QuickTime and what makes QuickTime better than
DirectX?

You'll need to give me more information about what you're doing, but probably the thing that I miss least about learning QuickTime is that I don't have to deal with COM. DirectShow is an architecture that is more or less in maintenance -- as far as I can tell Microsoft are concentrating on Windows Media, but WM can't do everything that DirectShow can at the moment. With Apple, everything is with QuickTime, so there is just the one architecture to deal with.
