I don't have any problem playing videos with the 20Mb package, in fact I can play 2 at once in HD on Netflix if I want to. You probably aren't really getting 20Mb or it's intermittent and not providing a constant high speed. Here's an HD video that I uploaded and I can play it just fine full screen without any problems. The buffer stays quite a ways ahead of the part that's playing and I can even play another video in HD at the same time. It looks like they downgraded the video quality a bit but it still plays OK full screen while a Netflix video plays in HD too.
