Not sure how it's "interesting" that it sits between a cable box and a television. It's just a capture device. And I think this it the third model. I have the first one, which is component-video only. Clunky, especially when it comes to channel-changing. Also needs a reboot every now and again or it just locks up. For my needs, the original HD-PVR is enough. Every channel on my cable box is protected with "copy once," so the added HDMI capability is of little use to me. However, the quality hit is barely noticeable and I do use the snot out of it.
Walking the fine line between jaw-dropping and a plain ol' yawn.
