I'm afraid not.
What would be really cool, is to see those nifty jumps during the matches.
You could start off simple. Every time you have a cool move during the match or kill several enemies in a short period of time or whatever is cool, you could write down the time of the situation (you can do that when there is a 5 sec break between rounds). Later, when you have lots and lots of situations you can start looking at your demos (ofcourse, after having a good match, move or rename the demo somewhere where u can find it easily) and then capture it. Try to be as high on the quality as you can, because looking at those 19fps movies with lame quality isnt fun. Places like youtube dont require you to download the movie, so if the movie has good quality but filesize is big, its not that much of a problem.
For moviemakers dp is a bad place, because you have to watch the whole movie until you can capture the situation at the end of the demo. I heard theres some tool jits made, but Ive never tried it..
