I've found that the problem ain't the webcam software, it's the driver
that ain't supported by your OS. Webcam drivers built into Windows
are a JOKE. They typically capture at the lowest possible resolution
with no way to change it. The rest is moot if the resolution is
unusable. No updated webcam vendor driver, means you're hozed.
