Hi all, I think I know the answer to this but wanted confirmation. We were recently given a Panasonic 4K TV (TX-50CX700B) which I've got connected via my Yamaha RX-V375 AV receiver to our Virgin V6 box (and other devices). The V6 has 4K capability and I've recently discovered that the AV receiver allows 4K pass-through, which I didn't realise. However, although watching movies on demand via the V6 box seems to work in 4K, the BT Sports 4K linear channel does not work. On the output settings of the V6 box, it allows 4K 2160p pass-through as an option, but not the 4K 2160p without pass-through. I've been reading up about this and it seems it might be because my receiver is a few years old and doesn't support HDCP 2.2, which I believe the TV and V6 box do. If this is the case is there anything I can do about it? Could I connect the TV directly to the V6 and run the V6 sound to my receiver via an optical cable? Any help would be greatly appreciated!
