My prediction: Tarrlok is Amon's brother (or at least a relative of some sort). Great breakdown of the episode. This one is easily my favorite of the series so far.

Have you looked into using VideoPress (http://videopress.com)? It's an addon for wordpress.com sites, but there's a plugin to work with standalone WordPress sites. (Basically, you signup for a free wp.com site, purchase the addon, install the plugin on your own site, then configure.) It's comparable to the cost of a Vimeo Pro account. Another option would be a site like Viddler which has a 500Mb cap per video, but it's free.
