Just got a Genius eMessenger 310 webcam, and I'm trying to change the capture resolution and FPS. The box says "Video resolution: CIF: up to 30fps, VGA: up to 30fps" but so far I've been unable to set anything other than 160x120 and what looks like 10fps.
I've tried Skype and VLC, this is the config dialog that shows up for both:

VGA SnapSize is grayed out but it refers to snapshots anyway. So no mention of resolution or FPS.
Has anyone been able to change these parameters or is this a scam and I'm just wasting my time?
