I have a Roku Ultra 4660X2. I activated it on my UK account. Everything fine except that iPlayer won't run.
I also have an Express which is working fine, but I wanted the 4K, audio support, and Ethernet port of the Ultra.
I guess this has something to do with the Ultra not normally being sold in the UK, but small world and all that - so seems crazy that its blocked?
There is nothing quite like the Ultra for sale in the UK.
So at the moment I have both the Ultra and the Express hooked up - my wife is very confused by two near-identical remotes from her point of view...
