When you play online games (in an internet cafe), you would most likely NOT WANT to see fellow customers who are video and audio streaming. The most popular of these, is of course, Youtube. See, when a video plays, the browser needs to download the video first into the temporary internet files, before he can view it...and videos are big files which takes up a lot of bandwidth to download.

So, a friendly advise for video streaming fanatics is to satisfy your hobby in places where you wont be a menace, like say, your own home, or a cafe which caters more to non-gamers like you. There are a few of them though, so good luck.

Now, aside from youtube, there are plenty of other video streaming sites you can go to. Some, can even stream you live tv channels (like hayag.com, a site i featured in my old blog at wordpress). Here are a few of them:
