Well I got the HDFury Integral this morning and it works wells. (from WiredNZ who are the only people who sell it in NZ) . You can get it from overseas but the price is compatible and getting it from a NZ Company gives me the CGA.
The only thing it came with a UK Socket USB Adapter and an UK -> "Export only NZ Pin Travel Adapter" Adapter which was illegal for WiredNZ to sell with . (This was in the well sealed package from HDFury themselves so they would of had to open the packaging and replace it to make it legal)
I "Fixed" that issue by not using it and taking USB power off something more legal.
Basically my problem was that my TV (65" 4K Sony KD65X9004A) did not do HDCP 2.2 but all my other devices did (Onkyo AMP and Roku) so I could not watch 4K Material from the Roku (Netflix,Youtube etc) as you have to have HDCP 2.2 all the way.
To cut it sort.. it works well. I placed it between the AMP (Onkyo) and the TV so now the AMP (and everything connected via it) thinks I have a HDCP 2.2 Complainant device and from the HDFury to TV talks HDCP 1.4. (Basically Its a HDMI 2.0/HDCP 2.2 -> HDMI 2.0/HDCP1.4 Convertor)
Now to wait for 4K Bluray Players to get to NZ .. Unless someone wants to allow me to borrow theirs?
