I have just added full episode videos to my Curb Your Enthusiasm site.  Every episode of Curb Your Enthusiasm is now available for download.  The quality of the videos is much better than the Seinfeld videos - but that means that each file is much larger.  The Curb episodes are between 150-300 MB each (compared with 25-80 MB for Seinfeld).  Click here to visit the CYE site and choose "Full Episode Videos" from the menu.  Enjoy!
