Hello, everyone. I have found out that the file descriptor gets blocked
when trying to read in the header for that particular MMS stream I'm
trying out.   

After it reads the first part of the header,  it does print out the
pragma lines fine. But, when it gets to the while loop that tries to
complete the header, it gets blocked at the read() statement.  Other
times, it  doesn't read anything. "i" returns 0.  This is strange
because fd does get configured for 0_NONBLOCK in open.c.

I can see that MMS does use HTTP requests for the initial connection
attempt. But, once that part gets read in, http.c goes out the window. I
think that we would need a completely new file for mms streaming.   I
couldn't see any references to mms in the ASF specifications.  I'm
trying to find out the format needed for MMS. (I think a new mms.c file
may be in order). But, I am studying the asfr+_1.4 
(http://yaan2.yeah.net) source code. It seems that mms is binary. I'll
keep studying that code some more.
