WinAvi Help?

Hi, ok, I made a topic on helping me convert my rmvb files and I was told to get WinAVi. I’ve gotten it and I need some help. How do I batch encode? When I try it, it converts the first file but when it gets to the next it says that it already exists and overwrites the file before it. Help?

Yea I think I told you to get it. lol. It is pretty simple choose which format you want to put it in (avi,dvd, or mpg) then choose your rmvb file. Then click convert.
