How is this popular? Video quality is absolutely useless, while it does at least render a recording, the HD downloads are with rare exceptions far worse than 720p, and playback is jerky and unmanageable with delays in loading and every time you change part video watching. While I yet to find a HD downloaders that really works with changes youtube has made, this also isn't one. Maybe if pay to register the quality improves along with removing the annoying QC watermarks it adds but I won't test that theory.
