My bad, did do a google search before posting but got a lot of unclear answers as to an actual card. There were results that most HDMI capture devices were copyright encoded which was useless for editing video.Well, no entirely, just by doing the google search you posted above he could have gotten an answer and research the product to see if it is any good.
If he would have specify something like I want to play over HDMI and record using component then things would get more complicated. He just said "I'm looking for HDMI capture device" which doesn't tell us much. If he want to record 1080p, then he better have at least 5 HDDs in Raid and a good PC to handle all that.
