Progressive download means that the browser downloads the file just
like it would (say) a PDF file, or a large JPG. The player will start
playing the video as soon as it has enough to start playing. If their
internet connection is faster than it is playing, then the
use sees the video playing just like it was streaming. If the
connection is slower than the video playing, then the player will pause
ever time it runs out of stuff to play.
You can control a little of this by the size and speed you encode the
video at.

You use the Flash encoder built into Flash (MX or better) The flash
help files will walk you through it. Flash 8 now comes with a stand
alone encoder.

That depends on how you have it on your site. If Flash video, you put
a Flash video component in your flash file. It comes with all the
needed buttons. If some other kind of file (wmv, mpg etc...) then you
can either have the player embedded in the HTML, or you can just
include a link to the file and let the user decide how they want to
deal with the video.

This depends on how you encode it. There is a thing called "Variable
Bit Rate" which allows you to encode a video at various speeds in the
same file. We have not had a lot of luck with this. We like providing
different links for different speeds. Let the user choose. If they
try one and it does not work well, then they will chose a slower one.

Broadcasting live events is not one of Flashes strengths. But you can
do it. Microsoft Media encoder, or real is much simpler.
