Hi Steve!
For playing videos, you can use ActiveX controls; you can use Windows Media Player ActiveX, but it doesn't perform very good with some AVI clips...
I suggest you to give a look at VIDEO LAN organization, which provides a free media player, with provides activeX control!
http://www.videolan.org/ Anyway, VLC is a good player, it's free and it doesn't ask you all the time to register, and stuffs like that, like some real does.....
Let me know how you managed!!!!

PS.: be careful installing VLC, you have to select for installing ActiveX control.
