While the info there is good (I initially used it) I stumbled onto something that is soooooo much better. I originall started doing videos that way but it caused me a lot of problems as well.

That links to a forum thread where a member of that community actually put together a little program to do the whole thing. So say goodbye to the command prompt and give it a shot.

It also sets up the folders and files that you need, so all you have to do is install bf2. From there open the program and select your bf2 directory and it does the rest.
