yes, i have checked it.
In fact it is the demo file i have downloaded the home page(the one used for 
comparison). i have put that file also in the rar if u want to cross
verify...(song.ogg)
I think it is a problem with how i am compiling it and how i created a
project in
VC++ platform. i saw in the maillist that there were some changes in
the code to
be done when compiling under MSVC, but no one has given a list of changes to be 
done. It would be helpful if someone could do that as all of us r not
experts in unix.

Thanks and regards

yes , i have done that. 
Changes i have done 
1> i've also added a #define for  'inline' to '__inline' 
in "misc.h"
2> i've removed the #ifder for endianness, and i've only put the
below
code for the union. but i dont think this will come into picture till
the file vorbis decoding actullay begins

union magic {
  struct {
    ogg_int32_t lo;
    ogg_int32_t hi;
  } halves;
  ogg_int64_t whole;
};

 3> Here is the code snippet i have added into the
"ivorbisfile_example.c" file
ie. i've removed the 'stdin' and given a FILE pointer to the
ov_open().
The file oprned sucessfully and also displayed the 'Ogg' string(i know
it will not display whole, just wanted to check if it displays the
"ogg" or not ie the start of file or not, It does display it so no
problem with fopen() )

//******************
  if( (ogg_file=fopen("song.ogg","rb"))== NULL )

      printf( "The file  song.ogg was not opened\n" );
   else
      printf( "The file song.ogg was opened\n" );

// for debugging if the ogg header was found at the start of file
 	   fscanf( ogg_file, "%s", &sa );
	   printf("%s",sa);

  //if(ov_open(stdin, &vf, NULL, 0) < 0) {
  
  if(ov_open(ogg_file, &vf, NULL, 0) < 0)  // Always returns -132 error
  {
      fclose(ogg_file);
      fprintf(stderr,"Input does not appear to be an Ogg
bitstream.\n");
      exit(1);
  }
//******************

My project file is in the current link, just checked it is working

(it is a file sharing webpage, did not get any other place to upload it !)
