Configuring httpd.conf

[b0bz]

Trying to follow the "engrish" instructions to configure the httpd.conf is well "improssible"

Here's what i want and where I'm at

I want to remotely access media files (stream to device)

I've done the following
1) installed the media server module
2) configured the dyndns account
3) Forwarded the proper ports in the router

I can successfully access the webserver remotely (see attached)

How do I set the security to prompt for a user and password?
Where do I place the media files so I can access them?

Maybe this total N00b but I couldn't follow the poorly written instructions

Thanks
