My server is in the central US. It usually can easily put out well
over a 4 Mbps stream, but on rare occasions it might be overloaded for
some reason. I have found that delivery speed outside of North America
often is much slower. For instance I can get a download rate of over
2Mbps from a London test site. However I get a download rate that is
much lower from much of Europe and other countries including
Australia. My computer is capable of over 5 Mbps, as measured, from a
test site. I am using ATT/ Yahoo DSL service which can give about 3 to
6 Mbps depending on how close you live to the local ATT phone company.
Of course slowdowns can occur anywhere between my server and your
browser, and there are lots of devices, cables, satellites, etc in the
link between my server and you. One reason that streaming .mov files
are not all that common, is that you require a really fast connection
all of the way to get the videos to stream well without partial or
complete download. The quality is very good, but .wmv or .rm files
often can work at much lower kbps speeds, with considerable loss of
quality and reduced image size.
What kind of QT player you have does not matter in playing .mov files,
be they regular ones or hinted ones for streaming. The QT PRO player
is one way to hint .mov files you wish to stream. There likely are
other programs that will create .mov files that will do this, but many
of these will be expensive pay programs that may include much that
many people do not need.
