I haven't played with it much (so YMMV), but I just recently found a web site that I thought other TVoIP members might find useful:
Apparently spreety doesn't even try to license/host their own video content. Instead, they are trying to be an online directory of other site's content. So you can use spreety to search for a show you are interested in, and then just follow the link to whoever is (legally) streaming that show. For example, when I looked up the old "Wonder Woman" show, spreety pointed me directly to the WB's web site, on the page to view that TV program from the 70s.
So on one level spreety isn't doing anything we can't (in theory) do ourselves, by simply maintaining shortcuts in our web browsers. However, I also know that it can sometimes be a challenge to find all the useful content out on the web. So I think a site maintaining a directory of other content (which is what spreety seems to be trying to do) might very well be of some use.
