That's ok. I enjoy watching the REC much more than the 6 Nations.
Rugby TV is a Portuguese Union run website where they stream all club and international matches live. It's proven to be quite popular.
All Rugby Europe International Championship matches are streamed on the Rugby Europe website at every level, including men, women, U20, U18, Sevens, Beach & Snow Rugby. They used to take their feed in full from local TV, so you had commentary in the host broadcaster's language, but now just offer their own filming with graphics and the ref's microphone. Some of the camera work and connections can be dodgy which doesn't help. There's not usually any commentary. Georgia v Russia was the first time they got their own commentary team in.
