Good video capture for Fallout

[Fallout1FTW]

I promised to show you guys my mod before this Christmas so I'm looking for a good video capture app. Any suggestions for what to use that is free and works good for Fallout?

I used Fraps, but Fallout must run in window mode, else all recorded screen is black.
