playing video when web site opened

how?

[dialectic]

a friend wants to add a video that plays when his site is opened how does he do it?

One easy way is to embed the video in Flash - you can be pretty sure that the viewing software is going to be there for most visitors.

But it's still a good idea to allow your visitors to choose whether to view it or not. Force feeding any audio or visual media has proven time and time again to chase away a significant section of the potential audience.
