I am looking for a provider where i can post my sample movie so my friends can see it. Any recommendations? Thanks.

www.yousendit.com isn't too bad for something that lasts for 7 days. What you do is upload your video to that site, put your own email address as the recipient, and post the link in the email you get from it in the forums. It only lasts for 7 days however, but you could resend it after 7 days and update your original post with the new link when it expires.

take a look at vimeo.com... your clip will be re-encoded, but they also provide a link back to the original clip you submitted, so you can see both versions.
