Although we now have a new Blu-ray players have a good YouTube app, I find the operation via an iPhone / iPad with the Chromecast something better.
The USP of the device is that now Arte +7 is Chromecast capable. I have on any other devices and also works perfectly. For this alone is a strong buy recommendation.
(The photos in standby are incidentally very attractive, but you would like to know where they were taken.)
