Watching TV on the internet...

So i've been wanting to catch up on some of the shows i watch on the SYFY channel on their website, but when i log in using my credentials i get an authentication error after the video starts playing the beginning advertisement. Specifically it will play the earlier episodes of Being Human, but anything within the last 3 weeks is a no go. I've signed in with the correct info, but no matter what it keeps telling me that the content is not allowed. Am i doing something wrong, or is this just the way it is?
