[*crvideo] (Insert Video ID here)
[*/crvideo]
Just go to any videos on crunchyroll, copy paste the video ID and you should be good.
Example:
http://www.crunchyroll.com/hunter-x-hunter/episode-73-insanity-and-sanity-
615501?t=0
So 615501 is the video ID.
Please let me know if you need further assistance.
