PS4 BBC iPlayer crash

I know this is a bit odd but i own a Asus 86u and have tried every version of Merlin from release, beta and alphas and for some strange reason the BBC iPlayer app will crash after say 5 or 10 mins on my PS4, all other devices work fine its just the PS4 plus all other apps work fine plus online gaming is ok on PS4

Have swapped over to my WRT 1900ACS running DD-WRT and everything is fine with the same simple setup ie just internet and WiFi not anything fancy while using a DrayTek Vigor 130...
