OK, 1st put the game in windowed mode:
C:\Program Files\Steam\steamapps\common\call of duty modern warfare 2\players, then search the config_mp and change seta_fullscreen "1" to a "0"
Then find a program that lest you record screen to a windowed size:
eg.Frapps, Hypercam 2, gamecam etc.
Once recorded, Convert the file size to make it smaller. This can be done with many free downloadable converters [check google (WATCHOUT FOR VIRUSES THOUGH!)]
Then upload to youtube to show off your major PWNAGE!!!!!
