In order for you or your users to start uploading video using Video Module, you must add a Video as a content type on your site.
Go to Administer->Content management->ContentTypes.
With the default installation, only users that have logged in can access/post comments.
This can be changed from Administer -> User management -> Permissions. The comments settings are self-explanatory. By default, registered users can post comments (they don't need to wait for moderator approvals).
If you want to let anonymous users post comments, go to Administer -> User management -> Permissions -> comment module.
