There are many MANY places to watch it online, but depending on where te are in the world and what programs te have installed on your computer (Adobe flash, DivX etc.) some will and won't work for you. What I would recommend would be to go to sidereel and click on the episode te want to watch. It will come up with a lista of different sites (not all will be free but just go back a page if they try to make te pay o do surveys etc.) and find out which one works best for you.
Here is the link:
link Once te find a site o provider (such as megavideo, supernovatube etc.) that works for you, just select that successivo time te want to view another episode. Hope this made sense to te :D
