V2 updates break BT TV AGAIN!

I am so sick of Netgear and the constant issues with Orbi firmware. With the version 2 updates BT TV is playing up again. This is something that was broken, then they fixed, then they broke again and then they fixed again in various firmware releases.

The multicast channels work for a couple of minutes then stop. A reboot of the Orbi fixes for a few minutes then they break again. Ive tried the latest firmware and a factory reset. It seems to have started with the version 2 releases. I want to ditch the Orbi but I'll only get a fraction of what I paid for it if I put it on eBay. I wish the Netgear developers could put out firmware without constantly causing new issues.
