Every BluRay player on the market with component connections outputs on those connections without HDCP as far as I know. This is the so-called "analog loop-hole."
It would seem this device is most useful for an output device that lacks its own analog outputs.
Every "HD-ready" TV out on the market should be able to legally display HD content from BluRay and other sources using an HD analog input.
Bottom line, if you have a device with component outputs you don't likely need the HDFury. An exception would be if said playback device limited the resolution output from its component connections.
On a similar note, if you want to capture said content (in HD) for playback on a computer (or HTPC), the HDPVR from Hauppauge has received very high marks. This is best suited for HD output from something like an HD settop box, because with disc content, you might as well rip the content from the disc directly to your PC (requires a BDROM drive and backup software of course).
