It makes a lot sense. I tried 
[root at workstation ~]# mplayer rtsp://server/share/potty.mpg
or
[root at workstation ~]# mplayer rtsp://server/potty.mpg

Both seemed made further. I saw "file format detected" message as shwon 
below. 

However, it seems there are quite Adecoder init failed while trying to 
streaming. What went wrong? For a comparison, I can play the same video 
file in a mounted nfs folder (the output is pasted below as well).

This is very dangerous (assuming you mean "log into"), but it is not
related to what I was talking about.

There are three different things being referred to with the word "root"
here: the root directory of the computer (which has the filename "/"),
the root user of the computer (which has the username "root"), and the
root directory of the server program (which can be any directory on the
server machine).

In the quote above, I was referring to the second and then to the third
of these.

That is not quite what I was asking.

The question is, what directory is your RTSP server configured to treat
as if it were the root directory?

That was obvious from the URLs you tried; it is not what I was talking
about here.

As an executable file, it should properly be in a bin/ directory
somewhere which is also in your PATH. It should very likely not need to
be run as root (this is a general principle), and therefore to avoid
security issues it should not be run as root.

> I always run it by entering

That is the server binary. What about its configuration files?

In one of the configuration files you should find a line indicating what
directory the RTSP server program will use as its root directory; this
is almost certainly not the same as the one the binary is in.

You need to put the files you want to serve under that directory
(subdirectories should be fine), and then leave out the path to that
directory when you are forming your URLs.

If, for an unlikely example, your RTSP server's root directory were
"/root/", then instead of "rtsp://server/root/share/hd.avi" the correct
URL would probably be "rtsp://server/share/hd.avi". Does that make sense?

If you do not know what the server program is configured to use as its
root directory, then you need to find out before you can make any files
available.

> I am not a linux guru although I wish to be one.

An admirable goal, though you seem to have quite a ways to go.

All of this discussion, incidentally, would be more appropriate on e.g.
a Live-related mailing list rather than on the MPlayer user list; so far
as I can tell your remaining problem appears to have nothing to do with
MPlayer directly, only with the way you are using the server.
