We watch the Geek and Sundry shows through the blu-ray's YouTube channel, so we can enjoy them as a family in a comfortable seating arrangement (instead of being huddled around a monitor). I don't think there's a way to thumb up through the channel. Or, at least, I've never noticed an option. If you are relying on these 'likes' in order to get a second season, is there a way to do that through the channel, or is just getting watched through a channel considered a 'like'?
