yeah Fraps is good, You can use it in any window.
But beware, that you need a powerfull PC ,
ELSE WHILE RECORDING YOUR GAME WILL LAG LIKE HELLLLLLLLLLLLLLLLLLLLLLLL! no seriously.... try it if you dont believe me..
orly... btw, fraps lags on an uber 1337 highend PC the same as on an old one, since its your harddrive that is limiting FRAPS' performance... so unless you have a bigass SSD, fraps will lag on every pc
