That's nonsense. AVI is a file container, and can host very many types
of compressed content. If you've watched a DivX movie then you've
experienced MPEG4 derivative inside an AVI container. There's no
"smallness" or "largeness" associated with AVI at all. It's what you
shove inside it that determines the bitrate needed to view it.

Again this is just nonsense. All modern media players will begin
playing the file when they determine enough of it has been
[progressively] downloaded to allow near uninterrupted playback.
That's what buffering settings are for, and operate on.

Sorry wrong again. A Streaming media file allows random access, a
Progressive Download doesn't. Streaming from a proper media server
means you get a miniumum initial download, enough to fill the players
buffers.
Using a term "downloading" in relation to streaming media is also
misleading, since the entire file never exists on the receiving
computer, unlike progressive download where the file *may* be cached
by the browser.
In addition, the player and server will often be arranged to "fast
start", i.e the server will try to maximise the initial delivery to
the player - up to 3-5x that of the encoded media file bitrate if
possible.
Both WMP and Quicktime can do this, not too sure about Real Player.
HTH
