Like Gminor said, the video has to be uploaded in HD in order to play HD, but. If you are not going to embed it in HD (1080i or 720i) then there's no point in playing HD content on a smaller size other than waste bandwidth and make your viewers wait longer for the video to download. You will not get better quality unless you watch it a the size is intended to.
In theory, if you try to play a 1080i movie on a 640 by 420 space, everything would look distorded, compressed and most likely skewed, that's why youtube will automatically stream a re-rendered version for your right size.
A good analogy will be, to scale up a 72dpi image to a 300dpi magazine, it would just not work (unless you have that "Enhance" feature from those police shows).
Or in the opposite, when you scale down a 300dpi image about 50% in photoshop and you still have the scaling handles (before you hit enter) the image looks bad, once you hit enter, photoshop re-renders that image to be displayed at that size.
