It would be nice if the menu activated by the eye icon gave similar options (theatre, HUD) when one is watching videos off their SD card as it does when watching youtube videos. It also could be nice to have the zoom function that is available on the youtube viewer when watching videos stored on the SD card as well.
I do like the way you have it set up, though, especially for youtube. The video viewers are set up more sensibly than others I've seen. Nice and intuitive.
