Maybe, but i never claimed to cover ALL aspects ;-)

It can, see below...

Browsers look for the MIME-type info in the html-source, which explains 
the browser
what plug-in to use/what (helper-)app to start etc...

Sorry, no idea...

I do all of the multimedia stuff/editing on my mac :-)

You can, of course, create files with QT that are playable on win...
(You will just have to avoid QT specific codecs...)

Like:

Audio:
AIFF with NO compression...*
WAV with NO compression...*
AU with µlaw 2.1 compression...*
(Important: 44.1, 22.05 or 11.025 khz sample-rate, 8 or 16 bit 
sample-depth)

Video:
AVI compression: Cinepak (low quality, but compatible)*
DivX (if you installed the macversion of DivX)

MPG (only playback supported QT)*

* Will also work on *NIX!

Chances are very good (NO guarantees!) that these formats can be played 
on
win WITHOUT QT...

Except DivX, these formats happen to be the ones that can be played 
with the
"play audioclip xxx" and "play videoclip yyy" commands ;-)

I would be a rich man, if i could answer this question ;-)

See above...

Check this page for further info about bundling QT with your app...
