Prateek,

Are you trying to demod the FM in the NTSC file I gave you, or are you
trying to demod a single FM channel that's already at baseband?

If you are trying to demod the FM in the NTSC file, please be sure to
update gnuradio-core from CVS and rebuild.  If you do that you'll get
Stephane's much faster (3x - 6x) complex dot product which is the
bottle neck in the NTSC FM demod.
