sdav: I'm big on the UX side of things believing that any technical issues can be resolved so my input is more around that. I think as it is right now is quite nice.
I would like to see the menu that appears on hovering over the programme fade in and out, makes it more pleasant on the eye. In this menu I would also like to see the rating and episode lengths too.
While in playback I would suggest the time counts down on the left rather than show the total time.
With your main focus on TV I think you should have an instant next/choose next episode menu come up 15-30 seconds before the show ends. Its good that it automatically loads up the next episode when you exit the player but I would prefer to stay in the player to go to the next episode if I'm so inclined to binge.
I think there could also be some more UX tweaks to make it even prettier but I assume this is not the finished (polished) UX?
Just minor things and I'm sure some of them have been mentioned already. It's the little details that when pulled off will smoke the competition.
Thanks sdav, good stuff that I (mostly) agree with.
