The massive stalling issues are probably a result of your ISP. I know that Comcast massively throttles YT video downloads after the first thirty seconds or so of the video have been downloaded. (I've verified this by directly downloading a particular video file at home, and at a Uni across the continent. The download at the Uni downloaded at maximum speed until the rather long video was downloaded.) [download, download, download!]
