Let this be a place to announce where series can be shown legally and for free.
Apparently, Aniplex of America has released the first 17 episodes of Durarara subtitled version on Hulu.
What a co-inky-dink, I just finished Durarara on Crunchyroll. ^^
You do have to pay for them, but I figured it was worth mentioning that Yumekui Merry episodes 1-7 are now up for purchase on Amazon VOD. Seems like it will be a while before it is released by sentai and they do not have the streaming rights to it so it's not going to show up on TAN.
According to this thread on Mania, Crackle secured the rights to stream the Viper's Creed TV anime series. All 11 episodes are now available on Crackle.
Also from Crackle, it seems that Ultraviolet: Code 044 will be streaming on the site. The episodes will be dubbed.
Edit: I already checked to see if it's true, and it is.
AniplexUS has one as well, but it looks like they only have one or two series for streaming. And I've watched some of their videos of Durarara!!, it's confusing because you have to press the close captioning button and turn the subtitles on yourself, but there's fewer commercials than other streaming sites.
Well here's the master list for those looking for stuff not listed here. http://www.mania.com/aodvb/showthread.php?t=88574
Thanks for posting this. It'll really come in handy when looking for legal streaming sites for new shows.
I use that Mania thread for the stuff I don't normally see, like TheWB or something like that.
