Yes, I've seen simple HDMI to USB video grabbers. But isn't these only
digital to digital video without A/D converter, which for me is the most
central part? Then it would be fine to get both HDMI and SD combined in
a single device, like in the above more complex and costly AVerMedia
device or also BM Declink, both with some HDMI (breakout) cable dongle
for analog connections.
