Matt: The screen off timer option under settings has listed: Off, After 15 sec, 30 sec, 1 min, 3 min, 5 min, and after 30 min... So yes, you can leave the screen on all the time. I set mine to 15 sec, because the battery life doesn't seem as good as my A800 series when I first bought that. And yes, you can create directories under the VIDEO folder. It's good to stay organized I guess. There's also an option to view 'All Videos'
Curiouss: Yes it is. It says 'Go to video playback screen.' I will say I miss being able to go Option > Now Playing from the main screen. Instead I would have to select the bottom right icon 'Go to song playback screen.'
