A Little Help?

Hey everyone!  I've recorded my first video tutorial, but it's 18 minutes long.  That means I can't upload it on youtube, and vimeo's never worked for me.  For some reason when I try to upload videos to it, it just doesn't do anything!  The Recording is an avi file; does anyone know how I can get it up somewhere so people can follow it?!  I can't upload it directly to my blog either; it'll compress it too badly...
