while it *should* work, please not that it has a 1 star rating, and likely will not work well. It would be easier to do this in analog (component is analog HD, while HDMI is digital HD) and go from DVI->VGA with an adapter, and then VGA->Component with a cable.http://www.amazon.com/Wired-Up-3-6m-Plated-Cable-Laptop/dp/B000P3Q0YW/ref=sr_1_2?s=electronics&ie=UTF8&qid=1329674418&sr=1-2
Note also that most analog TV signals are 30FPS/Hz, but computer output is by default 59 or 60, so there is a possibility of some issues with this setup requiring a converter box like one of these: http://www.amazon.com/Component-video-YPbPr-Converter-Up-scale/dp/B0016SN49Y/ref=sr_1_6?s=electronics&ie=UTF8&qid=1329674418&sr=1-6
Lastly, you need to know if your TV is Interlaced, Progressive, and 480, 720, or 1080. I have an old 'origional HD' TV which is 480p. It is technically HD... but hardly up to today's standards. Thankfully because it is progressive, and will recognize 60FPS signal (granted it only displays 24fps), I do not need a whole lot of adapters to make it work. Perfect for watching videos on it... but not so great for using it as a computer as the resolution is painfully low.
Best of luck!
