Talking of TV coverage, I was looking at RugbyPass.com but couldn't find any mention of ERC Challenge Cup coverage so I went on their "LiveChat" to ask. Yes they do cover Challenge Cup but only if you are in Asia. Oh, and don't bother trying to use a VPN they said, because your subscription to RP will be cancelled without refund...bit harsh!
Somebody on here suggested a VPN called "ZenMate" which has a free entry level. Unfortunately I couldn't find the free bit so have paid £8.99 for one months usage. When I actually find out how to use it (?) is it still worth trying to access RP despite all the warnings?
Update....it does work and I can now watch played/live games from anywhere in the world from my base in cough Hong Kong...EXCEPT any Challenge Cup content which just doesn't seem to exist...
