Free:

zed.cbc.ca good for short films
putfile.com

File sending/sharing services:
rapidshare.de
youshareit.com (similar to yousendit.com)


There's also a site where Vegas users can upload their stuff.

Web hosting:
powweb.com? They seem like they oversell the most bandwidth with the least strings attached (overage charges, terms of service that lets them terminate your account if you're using too much bandwidth)
I am using dreamhost.com right now, because of their 777 promotion for new customers. 1st year = $10
