If "down", try:
A video listing website.
Unfortunately, and as far as I can tell, every video streaming website they list has a maximum of 480p quality. It's passable for basic reviews and in lieu of a for-pay streaming service, but one must remember that hard-media purchases give not just proper quality but bonus features like commentaries.
While there are other such services, this one seems reasonably complete and has an active userbase. If you know of a better or supplementary service, please contact me.
Note: This website is blocked in the UK. See List of websites blocked in the United Kingdom. That looks like a great list to find other websites.
