Putting an DivX mpeg4 video file on the internet

I have a couple of home movies I'd like to put up on the
internet so my family (far away) can view them over
the internet.   They are .mp4 mpeg DivX files.

I don't want to "send" the files (via email or file sharing
apps), but rather, just have them view them directly in
a browser.

Do I need any special server to stream it, or what do I
need to do to do this?  Are there different ways to
do this?  (I'd like to go the simplest way possible, but
still get good results).

Thanks!
