I don’t know what this is about, but when I watch 16:9 videos on YouTube, I have 50 pixels of black on either side of the video. You get the right aspect ratio if you switch to a smaller player by clicking on the –><– button on the upper right, but then the video is too small. I haven’t seen any announcement from YouTube about it, and only a few people around the Interwebs seem to be complaining. I would like to put my complaints out there. Widescreen was a good idea. Pillarboxing is not. It’s even worse with 4:3 videos, although to be fair, pillarboxing on 4:3 videos is expected and not a big deal for me)
