IIRC it was on all but one episode of this season

You are right , nothing was filmed in Ireland .

One of the VFX companies is based in Ireland and so Bad Wolf can claim tax credits off the Irish Government , the logo is one of the requirements in getting the tax credit .

I wonder if that is the reason the BBC are allowing RTE to place it on it's player later this summer though that's not a requirement of the scheme .

I think it's just all the Irish fans complaining that they have no catchup access to it now as they can't (legally) access iPlayer but the Beeb has the rights to both countries. So it just makes sense to sell it to RTE Player.
