Yes, iTunes does install QT. However, not all PCs running Windows come
from the factory with QT installed. Many IT groups have their own
"Gold" build of what goes into their managed desktops. Having
delivered streams to thousands of corporate clients on managed desktops
I can state 100% that the majority do NOT have QT or Real installed.
However this ONLY pertains to the corporate market. In the consumer
space I would bet there is a huge QT installed base (remember 42
million iPod owners have QT on their computers).
My point was that streaming ISO standards will enable you to reach
close to 100% of the consumer market. In some cases, the user must
install a player (even Mac users have to constantly install new QT
players). BTW, the same also applies to streaming Windows Media. But,
when you look to stream to the corporate market, ISO standards
supported by QT have an installed player disadvantage.
There are also some feature differences between WMT and ISO. For
example, business users like their slide shows. With WMT you can
stream audio or video with a synchronized slide show in a frame next to
the streaming content. The WM encoder offers this feature as
standard. Real also offers this but their encoder does not support the
feature so you have to buy an overpriced product like Accordent or
build your own. QT does also support this but not in Broadcaster.
Only one QT encoder app (Live Chanel pro) supports scripted slide shows
but they don't support H.264 yet. NO ISO encoder supports scripted
slide shows. Of course, most consumers don't need this feature so
consumer webcasters are open to using the ISO codecs without having to
explain to their clients why the slide show does not work.
Like always, choosing a codec or format is driven by your target
audience and the features they need.

Isn't QuickTime installed on Windows along with iTunes? If so, how does that affect the proportions undergirding this argument?
