Looks like the "File not found" error is printed regardless of the
reason open() failed. Look at demuxer.c at about line 120:

    f=open(filename,m);
    if(f<0) {
      mp_msg(MSGT_OPEN,MSGL_ERR,MSGTR_FileNotFound,filename);
      m_struct_free(&stream_opts,opts);
      return STREAM_ERROR;
    }

I'll go ahead and make a patch to look at errno and print appropriate
messages for any errors that might happen.
