Live stream shuts off mid game if you are watching on time delay

I've been coming home too late to watch the Live Streams of the LCS / CS matches without a time delay. So I open the http://na.lolesports.com/ and click the current stream but it's already on Game 2 or 3. When this happens I go back to the start of the stream so I can watch the intros and Game 1 ect.

Except whenever the last game ends they turn off the stream and the thing I'm watching greys out and says "Broadcast Offline". Most times it's a couple of hours before the VODs are live, but it still really sucks to be halfway through a game and not be able to watch the end for hours.
