Media Player for different file formats

I wonder if you could help me.

I run a media website. I allow users to download videos and audios.

90% of my videos are in .WMV and some are in .RM and .AVI formats.

My audios are in .MP3, .RM and .WMA formats.

Now, I want the users to view and listen to these videos/audios before they download them. Can you tell me what I need to achieve this?

I think, I need a media player that I can include n my webpages, and provide it the link to each different file on my server. Which media player is able to play all of the above formats?

Waiting for the reply.

Thanks

I have played .mp3 .wma and .avi in vlc, but not real media. though i am in not sre u can use in webpages.

real one player is good for you

But I have seen RM Player and WMPlayer to be much slower in streaming the videos. Other Flash players start the video much quicker.

But I am not sure if I need to convert my videos to flash inorder to use Flash Media Players for my site

I would try VLC player, if you haven't done so already.

Yeah VLC (http://www.freeapps.co.uk/apps/vlc) plays pretty much everything
