I use Hulu a lot but I found these two places great also www.justin.tv and www.veetle.com you can pick what you want to watch but as anywhere on the net you have to be careful as sometimes stuff gets put on there that kids should not see, as a matter of fact some things I do not need to see! I find myself more and more watching the lifecasters on justin seems they are more entertaining than TV.
I want to add that these sites require a broadband connection I use DSL lite which is about 1.5 mbs and video works fine.
I’ll check them out.
