Does not work for videos that require decryption because
decryption is not working (giving 403) for some reason.

Partial fix for #146
403 errors on the video urls happen typically when a video has copyrighted content or was livestreamed originally. They appear to not happen (or at least happen less frequently) if the Tor exit node used ipv6, however.
