Funny draw (2 knights)

A slightly shameful draw here.  a) because I was playing a lower rated player b)because I couldn't remember whether it was finally a technical draw in the end game or not (it was) c) because I still played on suspecting it was and d) because I lost the plot and blundered into a draw.  Check out this video if you're interested in how you might just pull a win out of the bag in this situation anyhow.  http://www.youtube.com/watch?v=zCDN0Uey5Ns If you can spot where I could have got away with a sneaky win then kudos - it eluded me.  Also - mental note not to exchange down this way again or underestimate opponents.
