Playing Videos in asp.net

Hi

I am developing youtube like application where user can upload video and other users can see these videos.

Right now I am converting any video uploaded by user into .flv format.

Then for playing these videos I was trying to use a 3rd party flv media player.

But its not working properly.

What are other .flv players available that are compatible with asp.net, with the least functionality that video sharing sites should have. 

I tried silverlight , but doesnt support .flvs

Any suggestions?

Thanks in advance.
