First off, what is the quality of the stream?
Secondly, how fast is you're internet?
For example, say you have a 100mb line and were streaming youtube....needles to say you could stream a whole lot of clips.
But if you have a basic cable line (say 3mbs) you'd max it out streaming just one hd show.
so basically....I have no idea, you'll have to determine that for yourself.
