What is a small file size recording alternative to fraps?

[DarkDubzs]

I use fraps to record gameplay, but the preconverted file sizes are too big for extended recording as a few minutes is a few gigs. What is a good, free alternative to Fraps that records gameplay and records smaller file sizes, all with good quality. Any feedback or help is greatly appreciated

Have you ever tried MSI Afterburner (Predator is used for capture)? I believe an MSI card is required but I could be wrong. http/event.msi.com/vga/afterburner/overview.htm
