I'm going to comment some on the aspect ratio issues I have with lightbox. I realise it is an area of interactions and specific to titles but it really does let the platform down.
Randomly the first show I picked after the upgrade was "Watching Ellie". That is frighteningly bad aspecting. It's a 4:3 sitcom all the way stretched, and possibly more mods. I watched 5 minutes.
Next pick a couple of slots over, SGU. There was something very odd about the spaceship moving through the screen in the opener. Could be my visual processing was badly affeced by the previous experience.
Edit: love the new UI. honeymoon over. back to the grinching ; ).
