I have a no-name USB webcam that works fine if viewed directly as a camera on my PC.

The picture is great. I get the same behavior whether it is directly connected to the PC or coming over a powered, active USB 3.0 extension.

Using all default settings except selecting None for audio, the image is jerky. I have tried all of the NTSC frame rates and checked and unchecked the interlacing checkbox where available. Deinterlacing shows as none or blend when all is done. Is there some other setting I should be using? Is it possible that it just isn't compatible? The only options I have available when selecting the device are Sample Input, HD web camera, and my Panasonic camera.

Thanks.
