How to convert replays from game?

I was wondering if anybody can tell me how to convert the replay files from the arca so that windows media player can play them. Thank you

best way is to use fraps.. there is a link to it on the downloads on the website.. you can export them in the media center too.. but you will only see the car it is on.. and the files are some what big.. it is the best just to watch them in arca sim racing... but if you are wanting to upload them to you tube or whatever like that it is fraps and the the cyberlink program i have on the downloads page..
