QuickTime's player is completely irrelevant, I think. It works at least as well as any competitor, has a nice API, and runs cross-platform. Certainly, for my purposes, QuickTime support is essential, so if no-one else does it, I probably will :)
As an aside:
QuickTime gives you Flash support (usually one version behind, but then so are most browsers...)
QuickTime gives you support for almost all common 2D graphics file formats.
QuickTime gives you streaming download support.
QuickTime gives you a cross-platform GUI library (with native widgets).
And much, much more.
