Comcast On Demand?

I just found out about Comcast offering the Anime Network, free on On Demand. As well as HBO/ CiniMax, TMC, and much more all for free, only with the On Demand service. So I have the ability to watch these shows for free, at anytime I want. (Good thing I stocked up on VHS tapes, but I think its now time to stock up again. lets see... a full Anime series will fit on either 1, or 2 tapes, depending on the length of the series (average is 12 or 24 episodes.)
