You hadn't mentioned 1080p. The 360 only outputs at 60 fps in progressive mode, and the card can only handle up to 1080p30.
Ah but if you're only capturing movies say off Netflix from an XBox wouldn't a 30fps card be good enough? Because if you captured at the 60 passive it puts out you'd need to ditch every even or odd frame when it comes time to convert the capture back to its original frame rate. 30 or 24 or 25 fps.
