I'm a night owl
Anyway, I thought that at first too, that it was the software that came with it. But I had used Sony Vegas for video input from the USB adapter, and it had the same exact effect. The frame rate was bad, as in it would constantly start almost looking like a slide show every 5 seconds, go back to normal, then repeat over and over. The contrast of the colors was wrong and there was no way to fix it. I ended up returning it because it was utterly useless. You get what you pay for, it's better to get a decent PCI or PCI-E 1x video capture card even if they're older capture cards, but older PCI capture cards may require Windows XP or maybe they would work on Windows 7 in compatibility mode.
Here's a screenshot I made from when I opened an ebay return case:
