Is this just to stay away from QuickTime (that is cross-platform
already)? BTW, I know at least one new big enough Mac/Win project,
that is being written now, from the scratch and they use QuickTime
in it. I am not a doctor, but they definitely don't look silly...
[For that matter I know another big Mac/Win project that is being
written now from the scratch, that uses Carbon on the Mac side.
I haven't see those people to judge their health.]
