for playing videos in a web page, u have lot of players available...
1. flash media player
2. media player
3. jw player etc.,
and also you have different techniques to play videos on your web page,
i.e.,
1. Either by integrating(adding/embedding) the player object tag code into your html page,
2. Or in .Net, we have silver light, with silver light we can play our videos..
I am using flash media player in my project..
